It seems like I have my A CNAME and TXT records correct for my Azure App but My Domain name is still not resolving.
Error:
404 Web Site not found.
You may be seeing this error due to one of the reasons listed below :
Custom domain has not been configured inside Azure. See how to map an existing domain to resolve this.
Client cache is still pointing the domain to old IP address. Clear the cache by running the command ipconfig/flushdns.
Here is my source tutorial:
https://learn.microsoft.com/en-us/azure/dns/dns-web-sites-custom-domain
If you're getting that message, you probably haven't configured the domain as a Custom Domain.
In Portal go to the App > Custom Domain and make sure it's there.
If you do have it added, it's possible the A record is pointing to the wrong IP. You can check if it matches the one in the Custom Domain blade by running the following command in your command line:
nslookup <your domain>

I have created one azure web app service (S1:1), I have registered custom domain (TXT, CNAME & A records in DNS) for this site. I am able to access site using FQDN (https://xyz.pqr.com) but when I am using IP address to access this site it give me below error.
Why am I doing this?
I want to redirect another application to this application using DNS resolver for that it make use of IP address.
The 404 error occurs due to multiple reasons, please check the below to resolve the error:
Please check your domain resolves to the apps IP address by using whatsmydns.net
Please check whether the A record is pointing to the wrong IP address.
Check whether the custom domain is having correct A record and CNAME configured.
The old IP address may be cached, so trying to clear the cache.
Make sure the custom domain is present in the Azure App Service like below:
Please note that, using both a CNAME record and an A record for the same domain can cause a conflict and prevent the domain from being resolved.
Please check this MsDoc for few causes and solutions that may give you a pointer to solve the issue.

Free managed app service cert creation/generation failing with below CNAME error:
Error:Failed to create App Service Managed Certificate for hostname Subdomain.rootdomain.com. Click here for more details. Error Details: Properties.CanonicalName is invalid. Current CNAME records of the hostname are Subdomain.someotherdomain.com,subdomain.trafficmanager.net,subdomain.azurewebsites.net
I was able to repro and make it work if my CName mapping is via subdomain to my default *.azurewebsites.net.
However, the issue seems to be appearing when my CName points to another subdomain before the default *.azurewebsites.net as seen in error message below:
Any insights on this issue is appreciated?
You are seeing this behavior as it’s not a supported feature in Azure App Services yet.
While generating managed free certificated azure will run certain checks on domain and looks for a valid CName ie, either pointed to “.azurewebsites.net” or “.trafficmanager.net”
In order to solve this problem please follow below steps in order:
Remove Cname Subdomain.someotherdomain.com (sub.devopsauthor.com), make sure there is only
one Cname which is pointed to either “.azurewebsites.net” or
“.trafficmanager.net”
Now attempt to generate the Certificate and bind it to domain.
If you still want the Subdomain.someotherdomain.com after cert
generation, you can readd the Cname.
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

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.

I'm trying to bind my azure website to a third level domain.
This is my configuration on the Azure portal:
This is my domain provied A-Record console:
And this is my domain provider CName-Record console:
With this configuration the application works on http://www.test.mysite.biz but it doens't work on http://test.mysite.biz
(on http://test.mysite.biz it is displayed a page "domain reserved")
What Am I doing wrong?
Thanks a lot
You need to add another cname to your website
awverify.test pointing to awverify.yourazureapp.azurewebsites.net
check on https://www.whatsmydns.net/ to verify that awverify.test.yourwebsite.biz it is pointing to awverify.yourazureapp.azurewebsites.net
For the last two days I've been unable to create a CNAME from my domain to my blob storage account. I've registered the domain and added a CNAME that points to verify.azure.com on my DNS settings, but whenever I validate it (even after waiting a few hours), it never seems to validate... the error I get the Azure portal is "An unexpected error occurred while validating the domain name. Try again later."
Are there some issues going on?
verify.azure.com will only authenticate that you have the proper key to your domain however you would need another alias to set the proper CNAME configuration. Based on what you have written above you are pointing your host to verify.azure.com, however have you setup your storage subdomain alias to your storage name as well? If you have setup both the entries correctly, and still see the problem, at your domain registrar level there are some logs available which you can request for further troubleshooting.
