I am trying to setup fresh instance of OpenAM. I am getting “Invalid Host Name” error at the last of the configuration. I am trying to integrate it with my existing OpenDJ instance. I have set my hostname properly as FQDN. It is set in /etc/hosts and /etc/sysconfig. I also verified it with hostname cmd and it is perfectly matching. I am trying to deploy OpenAM 13.

I created the Container App where i would like to access from its website using host url
My container app into the vnet and it is having specific resource groups and and it contains specific NSG rules
Also, I have created and configured the private DNS zone in which I create a Virtual Network Link associated to VNET,
than I added a dns record set with name *.[same container app address] and container app ip address
When i tied to access the container app using app url i am not able to access it is showing the below error
{"statusCode":404,"message":"Cannot GET /","error":"Not Found"}
when i close ad reopen the url again got one more error
I deleted entire app and created newly got the one more error
Any help will be needed, Thankyou.
I tried to check same in my environment and got the below results
I created the virtual network with subnets
After that created the container app environment
If I check the application URL in the browser I am not able to access because I did not set the private dns zone record set
created the private dns zone and linked with the virtual network
I have added the dns record with container IP address to access the web
When I check in the command prompt I am able to see the that my container app URL is working
nslookup app-container.icycliff-187ffXXXXXXXXX.io
When check in the browser using app URL I am able to get application
NOTE:
1). After creating private dns zone must add the dns record with container app static IP address
2). 404 error message when website content has been removed or moved to another url
3). server responsible for the website is not running or the connection is broken
I'm trying to deploy a JS app (back in nodejs, front in reactjs) on a hosting server. I've dockerized everything (back, front and database) and everything works well, I can access my app through the IP address of the server.
Now I'm trying to setup a domain name to point to my app.
I've a Invalid Host header when I try to access from domain name (while still working accessing through server's IP address).
I've tried to add a HOST:mydomain.com to the .env of my reactjs app but I got this error Could not find an open port at mydomain.com
Would love if someone can help me through this :)
Given app works by IP, you can leave config of app as is. Do not add HOST or any other config.
IP to name mapping is done using DNS. So made DNS registration in DNS zone like this
mydomain.com A <IP address of app>
Where A is DNS entry type. Or made request to provider to register A entry type for you.
For testing purposes you may do mapping on any Windows PS using hosts file C:\Windows\System32\drivers\etc\hosts where mapping is done by
<IP address of app> mydomain.com
hosts works on one PC only.
After adding to hosts or to DNS try ping mydomain.com to make sure that name is resolved to correct IP address.
Mapping on web server is done when one web server hosts several different sites on one IP. But when you use Docker it's best to have one Docker container for one service.
I have a simple Asp.Net Core Azure Web App that needs to make a http get request to an on-premise Rest service. This Rest service is hosted on IIS with bindings set only for port 443. I've setup a new Hybrid Connection in Azure and added it to the Web App. At the on-prem side, I've installed Hybrid Connection Manager and entered the connection string for the Hybrid Connection - this now shows as "Connected".
Problem is, when executing the line of code that makes the get request, the following error is thrown:
System.AggregateException: One or more errors occurred. (No such host is known) ---> System.Net.Http.HttpRequestException: No such host is known ---> System.Net.
There's an interesting blog post here: Microsoft Blog which states that the connections should be setup without using the fully qualified domain name (FQDN) - server name suffixed with organisation.co.uk. However, as far as I can tell, the SSL certificate for the Rest service requires the FQDN - otherwise it presents the error
There is a problem with this website’s security certificate
Does anyone know how to troubleshoot and work around this problem?
The first error is probably a DNS issue. As that blog mentioned
If you are using a fully-qualified domain name, you need to ensure
that it’s a name that can be resolved within your local network. (In
some cases, customers are running DNS in the local network, and it’s
that local DNS service that resolves the name.)
So, If you have to use FQDN in the connection string for the Hybrid Connection. You could use an FQDN which only could be resolved by local DNS service.
Alternatively, you could try to edit the hosts file to make DNS lookup preferably inside the on-premise network. Add a line in Rest service server hosts file (located in %WINDIR%\system32\drivers\etc) mapping the IIS server's IP to a name.
For example:
192.168.0.50 serverFQDN

I have WAF, Application Gateway and a VM in place in Azure cloud. I have deployed an application in VM, which is running on tomcate and on port 8280.
I have domain name www.abc.com. In DNS entry, www.abc.com is pointing to my Azure App Gateway on port 80.
I am able to access the my application using IP and port. for example:-
http://X.X.X.X:8280/MyApps/page1 and http://X.X.X.X:8280/MyApps/page2.
I am trying to configure App Gateway, so that when I try to open using domain name. My requirement is when I hit www.abc.com, it should redirect to URL www.abc.com/page1. I tried to setup the listener with basic type and also path based. But no success. When I try to hit www.abc.com, it throws error:
502 - Web server received an invalid response while acting as a gateway or proxy server.
The 502 error always shows that there is a firewall restiction from your application gateway instance to your backend VM. You can verify if there are blocking the traffics in the NSG associated with your application gateway subnet or VM subnet. Also, this might be caused by inproperly configuring the custom health probe. You also can get more reasons from this doc.
Moreover, you can confirm you have set the url-based path correctly. Pay attention to the path and port.
I've deployed my version in windows azure.
After that I've added sql database. When I trying to connect, it doesn't allow from local. So I've clicked on "Set up Windows Azure firewall rules for this IP address" and added ip address. Now working fine when I run from local.
But When I tried to access from the iis8, I got an isssue is,
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - No such host is known.)
.Net SqlClient Data Provider.
In local, the same functionality is working fine.
Your server running IIS8 needs to be added to the firewall just like you did with your local machine, you can do this either using the Management Portal or you can connect to your SQL Azure instance from your local machine and run:
exec sp_set_firewall_rule N'IIS8 Webserver','X.Y.Z.0','X.Y.Z.0';
Where the first arguments is name of this firewall rule and X.Y.Z.0 is the public ip of your IIS8 Webserver.
The reason its specified two times is that you can specify a range of IP's.
