Internal Server Error

Getting advice
1

Hi there,
I am new to keycloak. Manged to install it, setup my first realm beside the admin one, did a few tweaks for 2FA and put it behind a reverse proxy (Traefik). Everything went well until a short time ago. I guess during the last week something happend and now I only get “Internal Server Error” after login.

For I am new to it, I am looking for guidance what to do in such a situation - like eliminating HTTPS, certificates, reverse proxy - and access the admin realm through plain HTTP. Or in which logs to look to trace back the error.

I changed a bit in keycloak.conf for the reverse proxy hostnames and configured logging on the root level. But even setting log-level to DEBUG, I don’t see any WARN or ERROR message in the logs.

In the end it has been a CA certificate change at Let’s Encrypt, that I missed to apply to Traefik. A hint in another forum to look at Traefik logs led to the solution.
