Unable to create custom domain on Azure app service (Web app) and Static Web site

Question

Hello,

 

We have a problem to add custom domain to our Azure app service(Linux).

Validation is passed, but on Add se got error “Failed to add custom domain” and when we go to Activity log details message is

{"error":{"code":"BadRequest","message":""}}

 

Our domen is on the CloudFlare and we added new subdomain that we would like to connect that subdomain with custom domain of our application.

 

When we do DNS check we could see that our domain is propagated.

 

Does integration of Azure Custom domain with Cloudflare has any issues?

Could you recommend us some resolution steps?

 

 

Thanks!
