Describe the bug

After several weeks since the last update of our application, I tried to upload a new version to testflight. Unfortunately all commands tns apple-login and tns appstore fail with

The server returned unexpected response: Unauthenticated

Request ID: <id-string>.0.0

Using the same credentials to log onto any of the apple developer websites continues to work fine.

Any idea what’s going wrong here and how to fix it?

Thank you. That also did not work at first, but this way I found the signing problem that apparently got introduced with an XCode or MacOS update.

All right, after lot’s of searching and finally opening the correct .xcworkspace instead of the .xcodeproj file, Product > Archive has worked. Thanks to apple for only showing the folder in the project open shortlist 😠

So I’m back at the initial problem, ns appstore ... still does not work.
