How to determine, diagnose, and fix issues that you might encounter when you use Traefik Hub.


Troubleshoot certificate related errors.

The certificate is not trusted because it is self-signed

It is possible that you see this error during the initialization of Let's Encrypt certificates. Once the initialization succeeded and the service uses the new certificate, this error goes away.

If you experience that the message is persistent, please restart your Hub Agent and check your logs for errors.

Not Trusted Certificates

Generating a Let's Encrypt certificate for new domains requires more time than exposing the service. It might end in a window where the service is available with the wrong certificate.

During this time, Traefik Hub serves a self-signed certificate.
