Similar to this issue Can't setup Discourse ID: Application with this redirect URI already exists My self-hosted Discourse has this exact error. But the thread above was already closed and didn’t see the answer on how to fix, but happy that issue was resolved. Is it possible to help my forum as wel…

This should be resolved via PM now. The original issue was that this instance was registered a while ago, the server has issues, so the site manager had to reinstall Discourse and the credentials didn’t carry over.
