Universal Links not working on an iOS 15 device with the associated website

Prior to iOS 15 our Dev server was routing universal links to our test devices just fine from both Xcode and TestFlight builds. But now we have taken the latest build from my Mac Big Sur and created new ipa build then we've started testing on iOS 15 devices the Universal links aren't working with the same existing code.

What is the server-relative path to the AASA file? It should be something like:

https://your.domain.or.subdomain/.well-known/apple-app-site-association

In the past, the file could alternatively be located at the root path (https://your.domain.or.subdomain/apple-app-site-association), but the .well-known subdirectory is now required.

Thanks for the reply.

Already the file is present in that path .well-known. https://mydomain.or.mysubdomain/.well-known/apple-app-site-association.

Still the universal link is not working
