I have an app on render and want to allow users to add their own custom domain so they can view their profile using their own domain.
For this I added a CNAME record in my DNS which will eventually return user profile based on the host name.
To test this, I used another domain, added a CNAME record in its DNS (cloudflare)
@ - cname.myapp.com
When I visit my test domain which should return my user profile based on the host name/ custom domain I saved in my account, instead it throws Error 1000 from cloudflare.
