Failed to synchronize abc@xyz.de account with Apple Developer Portal.Failed to resolve forward links for Apple Develop Portal client

I'm loosing my nerves with this apple products...

i want to add my Apple Developer Account to Visual Studio for Mac (V8.10.4 Build 11).

But I get this error:

"Failed to synchronize abc@xyz.de account with Apple Developer Portal." "Failed to resolve forward links for Apple Develop Portal client. Reason: Please check your internet connection or try again later."

Without these I can't load my app to App Store Connect..

My internet connection is working fine, everything else works fine.. My Account was accepted by Apple and I accepted all agreements on App Store Connect.

Please help..

As mentioned by @ShrikantDandile in the comments above. Following worked for me too:

1. Go to Visual Studio -> Preferences -> Apple Developer Accounts
2. Remove existing account
3. Close the solution currently open
4. Create a new app - TestApp or something
5. From the menu, go to Visual Studio Select Preferences Under publishing, select `Apple Developer
6. Accounts` Remove existing account and add it back again
7. Close the TestApp solution
8. Open your actual solution and you should now see your apple account and profiles in place
