I added a custom domain name for an Azure API App (actually on the underlying API app host).
The `https://microsoft-apiappXXXXXXXX.azurewebsites.net/ address still works but the custom domain yields the following error in the browser:
<Error>
<Message>
No ApiApp installed that can handle forward request to https://my.customdomain.com/
</Message>
</Error>
I've configured a custom SSL certificate, but with or without it, I get the same issue (minus the SSL warning when the custom SSL is not configured). HTTP access just issues a 302 Redirect to HTTPS.
Any ideas?
Unfortunately this is a known limitation of the preview bits when using custom domains. When I replied on the original thread of yours I didn't realize that, my apologies.
It's on our backlog and the team is working hard to get this implemented. It's a very common scenario so I don't think it will take much time (maybe a couple of weeks if everything goes ok) but I don't have an exact ETA to share at this point. I'll update this thread once it's live, it shouldn't be long.
You can find a list of known issues here, we will update it to include this as well.

my Node.js server is supposed to send a GET request to a third-party website vie https.get, but that website returns a 503 error, which is strange, because when I send the exact same request from my own device everything works as intended. Does anybody know what may be the cause of this problem, and how it can be fixed?
EDIT: The website uses CloudFlare, it might be related to theproblem but still - it works in my device.

I've been using Azure to host my Web Apps for a while now and they've had my own wildcard cert attached to various ones with no problem. Recently, however, one of my clients has wanted a certain degree of uptime/performance (not that there have been any problems so far but they are willing to pay for it and who am I to turn down money) so I've set up mirrored sites and am using traffic manager to route between them.
It works like a charm but for one problem: I have a cname pointing a friendly url to the traffic manager address and, if I try to connect via https, it craps out and wants to use its own *.azurewebsites.com cert no matter what I try.
So my question is: am I missing something here? How to I use my own custom *.mycompany.com cert in this case?
Or, for that matter, is there a better way of doing what I'm ultimately trying to accomplish here?
Here is my set up:
Endpoint 1: MyWebApp-East (type - Azure Endpoint, ssl installed and proper host info added)
Endpoint 2: MyWebApp-West (type - Azure Endpoint, ssl installed and proper host info added)
Traffic Manager: Routing Type - Performance
UPDATE
Oddly enough, I got it to work. I must have had something wrong somewhere. I did a scorched earth approach to it by deleting EVERYTHING (sites, traffic manager, dns entries, etc) and starting over. It works perfectly now!
Posted this in the top part but so as not to leave this open, I'll repost the solution I found:

Sometimes to go forwards, you have to destroy everything.
I've got 6 identical machines running IIS and Apache. Today one of them decided to just stop serving requests. I can access all of the webapps when I try from localhost/resource but when I try from url/resource I get a 404. I did a Get request against the machine that isn't working and I get this back:
Server: Microsoft-HTTPAPI/2.0
Connection: close
Compared to a working server:
Server: Microsoft-IIS/8.5
X-Powered-By: ASP.NET
Content-Type: text/html
Tried searching for this problem but came up with nothing, anyone got any idea's?
Windows has an HTTP service that manages calls to IIS and other HTTP enabled services on a windows machine. Either you need to configure it to handle your calls, or, in the case of WAMP or similar non-IIS-web-server-on-windows scenarios you may just need to turn it off.
When you see "Microsoft-HttpApi/2.0" returning error, such as 400 "bad URL" or "bad header", etc. the problem is most likely because the HTTP.sys service is intercepting your http request and terminating it because it does not meet with the minimum validation rules that are configured.
This configuration is found in the registry at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters. In my case, it was choking because I had a RESTful call that had a 400 character segment in the url which was 160 characters more than the default value of 260, so I
added the registry parameter UrlSegmentMaxLength with a DWORD value of 512,
stopped the service using net stop http
started the service using net start http
I've run into these issues before and it is easy to troubleshoot but there is very little on the web that addresses it.
Try these links
"the underlying problem is that the client has sent a request to IIS that breaks one or more rules that HTTP.sys is enforcing"
enabling logging on HTTP.sys is described here
a list of the HTTP.sys parameters that you can control in the registry is found here.
A bit late, so put here for posterity ;-)
After trying all sorts of solutions found on the web, I almost gave up, but found this little nugget.
If the response's Server header returns Microsoft-HttpApi/2.0, it means that the HTTP.sys is being called, not IIS.
As a result, a lot of the workarounds will not work (URLScan, etc).
This worked however:
Open regedit
Navigate HKLM\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\
If DisableServerHeader doesn't exist, create it (DWORD 32bit) and give it a value of 2. If it does exist, and the value isn't 2, set it to 2.
Finally, restart the service by calling net stop http then net start http
src: WS/WCF: Remove Server Header
Set below registry flag to: 2
HKLM\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\DisableServerHeader
Setting this to 2 will ensure that self host WCF services no longer sends the SERVER header and thus ensure we are security compliant.
Please note that this disables ALL server headers.
The default value of 0 enables the header, and the value of 1 disables server header from DRIVER (http.sys), but app can still have headers.
For me I had to restart the server for the changes to take effect.
Hope this helps someone
I was working on our web app on a client's site and ran into an issue where the site root pages loaded, but the reports folder always returned a 404 for files that existed in the folder. The 404 page showed the .Net version of 2 when the application was set to 4, and a test of a non-existent page in the root returned a 404 page showing .Net 4.
I tried just http://localhost/reports and got back a Microsoft Reporting Services page. Not part of my application.
Be sure to check just the default document of the folder when a unexpected 404 comes up and the file exists.
This question and series of replies helped me get to the bottom of the related issue I was having. My issue centered around using just a subdomain to go to our server (e.g. typing "www/somepath" into the browser while on our corporate network), which had worked in the past on an older server, but no longer worked when the system was upgraded to a new server. I saw the unexpected Microsoft-HttpApi/2.0 string in the header when using the Chrome Devtools to inspect the Network traffic.
My HTTP.sys process was already logging, so I could verify that my traffic was going to that service and returning 404 NotFound status codes.
My resolution was to add a binding to the IIS site for the subdomain, making IIS respond instead of the HTTP.sys process, as described in this server fault article - https://serverfault.com/questions/479274/why-is-microsoft-httpapi-returning-404-to-my-network-switch
In my case, running Windows 10 Pro, it was the Windows MultiPoint Service.
By executing:
net stop wms
Port 80 was released.
I've got a fairly simple app deployed on OpenShift that uses CloudFlare as a DNS provider, since they support CNAME records for the root domain, which our current domain provider does not.
The issue with this setup is somewhere along the line https is not working. I believe this is an OpenShift issue because it's the same kind of issue you get when you've mapped the domain name to your app but haven't added the proper aliases yet - you get a timeout essentially.
We've got two aliases - with www and without. There's no option to specify https or anything with OpenShift aliases from what I can see. There aren't any SSL certificates assigned to these aliases as we do not need or use https - we're on the Free plan.
The main URL to access the site is http://www.jcuri.com - notice this works as expected, however https://www.jcuri.com times out.
Initially we were thinking of using CloudFlare page rules to auto-redirect to a non-https URL however this is locked down behind a paywall which we're hoping to avoid, as we don't need any of the Pro features.
Is there something I'm missing here? It seems that OpenShift is just denying any https connections purely because we don't have certificates assigned to the aliases. I wouldn't even mind if there were certificate errors, at least that would give us a chance to do a redirect on the actual NodeJS application, but we don't even reach that point.
Can anyone offer some advice on this?
Since those domains are not pointed directly at openshift via CNAME, but are seemingly redirected via another service (from what i can tell from the dns) it is hard to say whether it is OpenShift that is causing the https issues. If you do not have a custom ssl certificate installed on openshift, you will just get an invalid certificate error, but since you are using a redirect service, maybe it is possible that the service is checking the certificate first, seeing an error, and then not working?
Since the https page rules you stated above are behind a paywall, this actually makes a lot of sense that they are blocking it, not OpenShift. Godaddy provided a forwarding service that would allow you to point both www and naked domain to openshift correctly using cnames, i have used it before.
I would appreciate any hints regarding the following issue:
The problem summary:
While using Negotiate:Kerberos in IIS 7.5, the authorization works correctly right until we setup URL rewriting (using the MS module "URL Rewrite 2.0") - any rewritten URL then returns "401.1 Unathorized" (requests not matching any rewrite rule keep working though).
The setup:
Windows Server 2008 R2 x64
IIS 7.5
URL Rewrite 2.0
Server is in a domain
SPN exists for HOST/hostname and HOST/hostname.domain (created by default)
Pool is using default ApplicationPoolIdentity (no custom account, not network service)
Kernel mode set to OFF
Authentication providers set to "Negotiate:Kerberos" only (no NTLM or annonymous)
URL Rewrite rule as as "^(.*)/$" => "index?x={R1}"
The result:
1) When accessing any URL not matching any URL rewrite pattern, Kerberos is working correctly, i.e. Kerberos ticket is issued (verified using klist), sent (verified using netmon and HTTP headers) and accepted (verified by URL being accessible and appropriate AUTH_USER property set to my domain account name) => no problem here.
2) When accessing any URL matching URL rewrite pattern, e.g. "hostname/foo" the result is:
HTTP Error 401.1 - Unauthorized
You do not have permission to view this directory or page using the credentials that you supplied.
Module WindowsAuthenticationModule
Notification AuthenticateRequest
Error Code 0x80070055
Requested URL http://hostname/index?x=foo
Physical Path D:\wwwroot\
Logon Method Not yet determined
Logon User Not yet determined
(if we try to access the rewritten URL directly, e.g. hostname/index?x=foo, Kerberos works again normally)
The attempts to solve it so far:
After googling, we have tried several options:
turning kernel mode ON: Kerberos stopped working completely, using either default pool identity or network service (I suppose we would need to setup additional HTTP SPN and/or use custom domain account with additional SPN for that account explicitly)
turning "useAppPoolCredentials" ON: no difference
enabling "Failing Request Tracing": surprisingly these failing 401.1 requests ARE NOT generating any output into the fail logs no matter what rule we try to setup (e.g. 400-999) - the folder is just empty (while other errors, like 404 or even handshake 401.x when accessing not-rewritten URLs are generating logs - very strange)
The conclusion:
So far we have reached a dead end - it may be some weird kind of "double hop" issue requiring using a custom domain account rather than default app pool identity, but as we're in fact accessing the same resources, it seems more like a URL Rewrite issue.
Any tips, hints, pointers? Anything would be highly appreciated.
Best regards,
Marek
we face the same issues as you do. By enabling extended error logging, we were able to put the finger on the actual problem, which seems to be a bug in the rewrite module (or at least in some part of IIS, which is related to the module):
When the URL gets rewritten, the access to the new rewritten URL is checked (seemingly hardcoded) using Basic Authentication and NTLM, neither of which has been configured on the Website at hand. The only configured authentication provider is Kerberos. Since the client doesnt send NTLM nor Basic credentials, there is no way this can work.
We (another person on the current project) are sending the issue to Microsoft. I will let you know, when I get any result.
It seems as though you have multiple issues here.
Failed-Request Tracing Logs
To fix your missing logs issue, you must make sure that the user that is running your site's AppllicationPool has read/modify rights to the folder where those logs are generated, otherwise you won't see anything. See the section labeled "Enable Failed-Request Tracing" on this page: Troubleshoot Failed Requests Using Tracing in IIS 7
What isn't clear is the fact that the site's Application Pool Identity (found in Advanced Settings for Application Pool) is the account that needs read/modify rights to that folder.
Once that is fixed you can load the XML logs in IE and see a much clearer picture of what is going on.
401.1 - Unauthorized Issue
A possible fix to your 401 error is to make sure unlisted file name extensions are allowed in Request Filtering. Go to IIS --> Sites --> [your site] --> Request Filtering
You have two options here:
Allow File Name Extension... and add the value "." (minus the quotes), see this answer.
Edit Feature Settings... and enabled the option "Allow unlisted file name extensions"
The 1st option should work well, the 2nd option obviously opens up a gaping hole but allows everything so you should be able to get it working.
I hope that helps.
