I have static website on azure storage, it's connected to azure cdn to have https, and i have my custom domain folla.com.pl I want this domain to point to https://companywebsitecdn.azureedge.net/ which is address of my website on azure cdn. I chose custom domain on cdn configuration site, it asks me to make dns mapping to verify ownership, so i make CNAME cdnverify.folla.com.pl to cdnveriy.companywebsitecdn.azureedge.net and it get me to other window with custom doamin https config. And here's my problem, it get's stuck on second step
How I'm suppouse to configure another mapping to make it work, what i mean is to make folla.com.pl to point to https://companywebsitecdn.azureedge.net/ with https. I can't proivde what i already tried with my dns because it was a lot and i don't remember all of it. Also it's already second try and everytime after failure I have wait 8 hours for another try. Thanks in advance
This is my DNS config
When you try to add your custom domain folla.com.pl in the custom domains settings of Azure CDN endpoint. Before this step, you should have a CNAME record in the following format in the DNS zone.
When you turn on the custom domain https, you don't need to make a CNAME cdnverify.folla.com.pl to cdnveriy.companywebsitecdn.azureedge.net. Read here.
If that CNAME record still exists and does not contain the cdnverify
subdomain, the DigiCert CA uses it to automatically validate ownership
of your custom domain.
If the CNAME record entry contains the cdnverify subdomain, follow the rest of the instructions in this step.
DigiCert sends a verification email to the following email addresses. Verify that you can approve directly from one of the following addresses and read here.
admin#<your-domain-name.com>
administrator#<your-domain-name.com>
webmaster#<your-domain-name.com>
hostmaster#<your-domain-name.com>
postmaster#<your-domain-name.com>
Automatic validation typically takes a few hours. If you don’t see your domain validated in 24 hours, open a support ticket.

my team and I are currently exploring using Azure static site blobs and CDN endpoints to host several web apps.
We have successfully deployed our static files to the blog storage and our entire test app loads on both the primary (name.abc.web.core.windows.net) and CDN (name.azureedge.net) endpoints. When it comes to mapping a custom subdomain via the “cdnverify” temporary step, however, I am unsuccessful.
I have very carefully followed and quintuple-checked all steps in the support doc "Tutorial: Add a custom domain to your Azure CDN endpoint" (here).
This is my current DNS config (via Namecheap).
When I skip the cdnverify step, e.g. assign the azureedge CNAME value directly to a host called “v2”, and add that as a custom domain in my Azure portal CDN blade, the subdomain begins loading the CDN endpoint and can even have a CDN-managed HTTPS cert deployed with no manual verification. A dig command to this host (v2.ourdomain.org) finds an expected response (view here).
Here's the rub, though. If I assign a CNAME host of “cdnverify.static” to “cdnverify.name.azureedge.net.” and add it as a custom domain in the portal’s CDN blade, however, this secondary subdomain never loads our endpoint, and cannot deploy an HTTPS cert. The Azure portal verified this host when added to the endpoint and a dig command to “cdnverify.static.ourdomain.org” shows this answer, which looks good.
A dig command to “static.ourdomain.org” returns no answer and a ping command says “unknown host”. This is expected since I’ve not created such a record yet, and so I am wondering how we’re meant to ensure this subdomain is verified as per the “Verify the custom domain” section in the above-mentioned doc.
It’s very important for us that the cdnverify host works and can be assigned a certificate before we permanently re-locate our domains as these apps are already in production. At this point, I am at a loss over what to try next. If possible, I’d love to know what step(s) I am missing, or what can further be done to diagnose the issue.
Many thanks to anybody who might have some advice!
The cdnverify subdomain is to create a temporary CNAME mapping to avoid interruption of web traffic. With this method, users can access your domain without interruption while the DNS mapping occurs. If you have not any existing web app work, you can skip the cdnverify step.
From your description, "a dig command to cdnverify.static.ourdomain.org shows this answer, which looks good." It indicates that the cdnverify host works and you have verified that. You just need to associate the custom domain with your CDN endpoint.
In this step, you enter your custom domain like static.ourdomain.org, including the subdomain. Do not use the cdnverify subdomain name.
After you have added the custom domain static.ourdomain.org successfully in the CDN endpoint.
At this point, your custom domain has been verified by Azure, but
traffic to your domain is not yet being routed to your CDN endpoint.
After waiting long enough to allow the custom domain settings to
propagate to the CDN edge nodes (90 minutes for Azure CDN from
Verizon, 1-2 minutes for Azure CDN from Akamai), return to your DNS
registrar's web site and create another CNAME record that maps your
subdomain to your CDN endpoint. For example, specify the subdomain as
www or cdn, and the hostname as .azureedge.net. With
this step, the registration of your custom domain is complete.
After you have completed the registration of your custom domain, verify that custom domain references your CDN endpoint.
Finally, you could freely remove the cdnverify CNAME record in your domain provider as it was necessary only as an intermediary step..

the company I’m working for provided me a subdomain. test.mycomp.com . I want to add it to my azure web app via custom domain.
The azure system recommends a CNAME delegation and provided me the information to enter web-zeudz-staging.azurewebsites.net in the dns management as CNAME.
After doing so and verifiying via DNS Lookup, Azure always gives me „Domain Ownership Error“. What can I do to make this work?
Is your DNS provider also a CDN provider, for example cloudflare? If so, turn off the CDN/proxy function so it's a DNS only record and try again.
If you don't have any control over the CDN function you can use txt record validation.
Create your TXT record awverify.subdomain.test.mycomp.com with value web-zeudz-staging.azurewebsites.net and validate again. It should succeed.
There's also a CNAME awverify method but you need CDN disabled for that too.
I find it strange that your company doesn't have the option to enable/disabled CDN for any given DNS entry though.
When we tried to add a custom domain to our current Azure CDN endpoint, the CDN was down while it was trying to verify and issue an SSL certificate for the custom domain. I cancelled the process and everything came back after a few minutes.
I know that in the instructions it states to map the custom domain to the temporary cdnverify subdomain,https://learn.microsoft.com/en-us/azure/cdn/cdn-map-content-to-custom-domain#map-the-temporary-cdnverify-subdomain, but I think this is only if the URL we are using for the custom domain is in use. Is this correct?
Is there any way to avoid this downtime or should this not happen?
but I think this is only if the URL we are using for the custom domain
is in use. Is this correct?
Correct. The link states that when you map an existing domain that is in production. First map your custom domain to your CDN endpoint hostname with the Azure cdnverify subdomain to create a temporary CNAME mapping. so you can access your custom domain URL without interruption while the DNS mapping occurs.
Is there any way to avoid this downtime or should this not happen?
If you have verified that the cdnverify subdomain has been successfully mapped to your endpoint, you can then map the custom domain directly to your CDN endpoint hostname. After creating CNAME for your custom domain, you can delete the temporary cdnverify subdomain CNAME record. It should avoid this downtime.
I am trying to set up a secondary azure website in a different subscription.
When creating the Custom Hostname for the new site location, I am forced to validate the hostname.
Azure complains that the hostname is registered against a different CNAME and prevents me from adding it.
This is true, but I don't care, I want this to swap over from the old website to
the new one when the DNS records propagate.
I the old IIS world, I'd have just added the hostname to two servers and when the dns pointed to the correct one, it worked.
Now in Azure it validates that the Azure Hostname I am pointing it to is correct and that the cname record already exists, it isn't 'valid' until I change the DNS.
I have to disassociate the current cname, then add to my new site.
I'm sure the only issue here is the "validation", there is no reason why I can't have the name in two places, dns decides which it goes to, not the end point web site.
I'd like to be able to set this alias, whether valid or not, so that when it becomes valid, it works.
The result I get is validation prevent me adding the hostname.
- I have to ask the client to change the DNS Record
- when they manage to do that, they will tell me
- only then I can go in to Azure and add the hostname to make my site work.
There is documentation for this exact scenario: https://learn.microsoft.com/en-us/azure/app-service/app-service-custom-domain-name-migrate
You can create a TXT record with host:
awverify.register.tourofmargaretriver.com
and value:
cyclingeventuresregistration-production-webapp.azurewebsites.net
This verifies domain ownership without directing traffic to it.
I am on a project that is re-platforming a site from a web server to an Azure PaaS web app, in addition the site will have all new content and in some cases new URLs. We have some redirects in place to handle the mapping of old URL's to new ones. I would like to test that these redirects work correctly on my new azure web app. Normally I would update my hosts file to point at the new server, add an IIS binding so the correct website picks it up and go from there. However I don't seem to be able to bind a new hostname ("custom domain") without verifying that I own the new host name. It will just be my internal DNS that I will be altering to re-route my requests. Does anyone know how to add a custom domain in the azure web apps without validating? This doesn't sound like a big ask to me.
Thanks
Will
You can't do it without any verification, but you can do it without pointing traffic away from your existing site to your new site.
To verify you own the domain without redirecting traffic to it yet, create a DNS record called a TXT record with your domain registrar.
the "TXT host" should be
awverify.mysubdomain.mydomain.com
or
awverify.mydomain.com
The "value" should be
myapp.azurewebsites.net
just replace "mysubdomain" and "mydomain" and "myapp" with your specific info.
After you do this, the verification should succeed and you can add the custom hostname.
Here is more info about this: https://learn.microsoft.com/en-us/azure/app-service/manage-custom-dns-migrate-domain
You can use either a CNAME record or an A record to map a custom DNS name to App Service.
We recommend that you use a CNAME for all custom DNS names except a root domain.
If you missed a step or made a typo somewhere earlier, you see a verification error at the bottom of the page.
If you will use A record, you can create a TXT record to map to the app's default hostname .azurewebsites.net. App Service uses this record only at configuration time, to verify that you own the custom domain. After your custom domain is validated and configured in App Service, you can delete this TXT record.
