Could that be just a temporary network glitch?

3

it still happens how can i validate it? validating the url gives me a 404

https://plugins.traefik.io/public/validate/github.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/v1.4.5

Now after 1 hour it worked again, but how can I skip validations? It can break all.

That's probably an issue you should address with the devs at Traefik Github.
