hey formost looking into this, thanks for your question. can you pls check/verify the Client ID and Secret and the redirect URI specified in Zitadel matches the one registered in Patreon exactly. Can you also pls check for the logs if they give any evidences docker-compose logs zitadeldocker-compose logs zitadel and look for Missing or mismatched user attributes OR Token validation failures. The error likely coming from a misconfiguration in either the Patreon OAuth2 setup in Zitadel or the NGINX Proxy Manager’s header forwarding. But you might have to provide more details
