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.

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.

Azure WebApps Custom Domain 404 error by AjayKumar-MSFT
Azure web app custom domain problem by Ryan Hill
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>
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.
Error creating Custom Domain in Azure
Hi, I am trying to link a custom domain to my static website that is located on my blob storage account. When creating the custom domain these are the azure instructions "Create a CNAME record with the DNS provider that points the domain (eg, www.contoso.com) to blobstorage.blob.core.windows.net or blobstorage.z13 .web.core.windows.net and then specify your domain. This method is simpler, but causes a short downtime while Azure checks the domain registration. "
In my godaddy account I have created a new CNAME record as follows Type: CNAME, name: www.mydomain.com, value: blobstorage.z13.web.core.windows.net.Y when trying to specify the custom domain in azure (mydomain.com) generates the following error: "Could not update storage account 'XXXX'. Error: The custom domain name could not be verified. CNAME mapping from mydomain.com to any of ..... does not exist "
I do not understand what I am doing wrong, I am very new in the subject and I really appreciate the help you can give me. Thank you very much
Be sure you have the CNAME record set correctly in the DNS settings for your domain name, then give it some time to update. DNS doesn't update immediately, it can take some time for the update to sync through all the DNS server between your registrar and Azure or your local ISP. This is especially the case when you test and it fails, then you need to wait at minimum the TTL (time-to-live) time that is set on the DNS records updated before you'll be able to test again.
On an aside, I'd recommend setting the TTL on the DNS records to 1/2 hour, then when everything's working you can go update it to a longer TTL. This will help when you need to update things and retest again to get it working.
I could already make the configuration I was looking for by configuring a CDN. this is the link learn.microsoft.com/en-us/azure/storage/blobs/… Thanks everybody fot your answers and comments –
I am using a Reserved (as of today called 'Standard') instance in Azure to host my website.
I have also set up my CNAME record from my domain provider to forward from www.{0}.com to the {0}.azurewebsites.net record, which works just fine.
The trouble I am having is with the A record. Currently
{0}.com gets a 404.
Under 'Manage Domains' in the Azure Management portal, it recommends setting up an A record to the supplied IP address (i assume the VIP of my deployment).
The problem is that IP returns a 404 when it is hit, so of course {0}.com gets one too.
Is there something I need to do on the Azure side to get the IP provided to direct to my website?
Along with the A name record did you add a CNAME for verification purpose as well, to point from awverify.www.{0}.com to awverify.{0}.azurewebsites.net ?
