Can not add Custom DNS to Azure Static web app

Question

I have a custom domain ending with .ru . I follow all the instructions. When I use DnsChecker I see that CNAME and A values are created correctly. However, I keep getting validation errors.

Hi ibrahim doğrusöz ,
Welcome to the Microsoft Q&A Platform!
Ensure DNS records (CNAME/A) have fully propagated, which can take up to 48 hours. Use for confirmation.

Ensure CNAME record points to yourapp.azurestaticwebapps.net.

For apex domainsan A record pointing to Azure’s IP may be required.

Ensure you’ve added the TXT record provided by Azure for domain verification in your DNS settings.

Azure auto-manages SSL for custom domains. Check for any certificate conflicts or misconfigurations in DNS.

Run nslookup or dig to check if the domain resolves correctly to Azure’s static web app endpoint.

If validation errors mention “invalid domain” or “not verified,” it’s likely due to DNS not fully propagating or missing verification records.
