Help: Traefik container stopped running, all apps inaccessible

[IsmailChabane]

My Traefik reverse proxy container has stopped running on my VPS and I can't access any of my applications anymore. The app containers themselves are still running fine, but since Traefik isn't working, all the URLs just return nothing.

This happened suddenly without me making any changes to the configuration. I have multiple apps that are completely unreachable right now.

Does anyone have any idea what could cause Traefik to suddenly stop running like this? I'm not sure where to start troubleshooting and could really use some help figuring out what went wrong.
