Getting 500 Internal Server Error (Error=URLBlocked)

Traefik Traefik v3 (latest)
1

Hello everyone,
I just got a really strange error within Traefik which I never encountered before neither found anything useful on the internet about it (Or I am not able to use Google correctly). So the error looks like this:

The whole dev environment actually worked 3 weeks before (I am using podman on the latest version with traefik and nextcloud as a container). I shut down everything as I went on holiday. Now after getting the latest image and powering up everything, I encountered this error and my nextcloud is not reachable anymore (Internal Server Error).

As I am working within an isolated environment, I do not have any URL's set in place. I have to use IP Address configurations and self-signed certificates. Does anyone have an idea what could cause this problem? If further information is needed please let me know what exactly you want to see.

Many thanks in advance!

It seems strange that the error is in "DBG" level. You are sure it's not from the target service?

Hey,
I double checked everything and this error does not come from the target service. I was able to narrow down the problem but I do not know how I can fix it. The problem lies within the rule what I have defined. I set an IP address within the Host variable:

Does anyone have some ideas?

Usually TLS certs are linked to domain names. Traefik selects the TLS cert for the secure connection depending on the Host() name, so maybe it doesn’t work with IP.
