Traefik Error

Error 500

500 are really difficult to debug.

Possible solutions

• Restart the auth proxy. If you get a 500 on a Ingress that has an auth middleware such as Oauth2, it may be caused by a bad certificate. The certificate is renewed but if the Oauth2 is not restarted, the old cert is still active.

Why a 404?

• Check the traefik dashboard for any middleware problem

Why a 418?

The noop@internal returns a 418 per default.

It happens when your middlewares on your route does not apply.
