Unable to auth new community

The auth is stuck in an endless loop

**Steps to reproduce**
1. sign up in buzz app
2. Click the create community button
3. Sign into buzz
4. Click connect buzz identity
5. Connect using code or manual
6. buzz local app throws pairing didnt finish automatically question
7. Buzz web throws: "The signed proof does not match this challenge. Correlation ID: 9b0f769b-289e-4aaa-a575-33c17b5c01d9"

Reproduce the flow in the Buzz app and web interface using the six listed steps, including code or manual pairing. Compare the local app's “pairing didn't finish automatically” result with the web error about the signed proof and challenge. Done means creating a community and connecting the Buzz identity completes without the authentication loop.
