Custom ___domain for CDN never leaves pending state, even after setting the TXT in the third-party DNS provider (Namecheap).
Example URL:
cdn.contoso.com
The API is bound to api.contoso.com and the web static page is bound to www.contoso.com.
I added the TXT record with the "Record Name" as the "Host" field in Namecheap DNS settings for the ___domain and with the "Record value" in the "Value" field.
The ___domain check in the App service in Azure had a button to "Validate", but there's no such button in the custom ___domain settings for the CDN.
In Azure, the only button available in the "Validate custom ___domain ownership" is a "Regenerate".

I understand that you are facing issue with ___domain validation. And you have added the proper TXT record but still it is not completed.In Azure CDN, ___domain validation can take a few minutes to 8 hours, depending on DNS propagation and record updates. If the validation status remains "Pending" for a long time, you may need to regenerate the TXT record or check DNS settings. Domain Validation Process in Azure Front Door
In the meantime, please try to regenerate the TXT record and see if it resolves the issue. Validation usually occurs within few minutes, but some time it may take up to 24 hours.
Based on the Domain validation states documentation here
If the ___domain validation state shows "Pending" for an extended period, it may indicate an issue with the TXT record propagation or DNS configuration. You may need to select "Regenerate" in the Azure portal to refresh the TXT record value and re-add it to your DNS provider.
And you informed us your ___domain is hosted in third party please try to validate it TXT record properly added or not.
Please check once if the TXT record is properly added or not using the following link: https://www.digwebinterface.com/
Check the below document for more understanding: Domain validation
- For further investigation please try to share the below information:
- Could you please try to share the Custom Domain name.
- And also let me know are using azure provided certificate or BYOC certificate?
Hope the above answer helps! Please let us know do you have any further queries.

2025-06-14T17:06:09.1+00:00 Hello Praveen, I tried in a different way.
Since I already have my "contoso.com" ___domain validated in Azure, I selected that ___domain and tried adding a CNAME pointing "cdn.contoso.com" pointing to the URL of the Azure CDN endpoint.
I'm using Azure provided certificate, since I'm using an already validated ___domain in using by the App service and Static webpage.I can share the ___domain name in the private chat.
Similar to how my Azure App service got configured with "api.contoso.com" and my Azure Static Website got configured with "www.contoso.com", but no luck.
I did test with the website that you provided and the CNAME is there:
