Was working before, no longer working this week. Trying to sign in to my Claude Pro account via Xcode Intelligence. Goes to browser, I login, and accept authorization in Claude then redirect back to Xcode is reject. Everytime, multiple browsers, and even trying the add "/" that others have noted for other cases.
Claude auth redirect failing
I have the same problem. I am not able to sign into my Claude account for the intelligence chat in Xcode 27
Happens to me with the codex agent in Xcode. The whole login with agents in Xcode is a complete disaster.
