Good afternoon, I hope you are well. I’ve been busy for a few days regarding the deployment of my cluster that I have already mounted and created the various services that I will need (GitLab and Grafana + Prometheus in my Rancher + K3S cluster).

The problem comes when I add an ingress for my Gitlab application and it doesn’t load the stylesheet. After this I say, “Yes, I have already done this” but it gave me an error that I have never encountered on my ingress traefik that I have set up.

The “https://domain-name/assets/webpack/runtime.bad33c1a.bundle.js” resource was blocked due to a MIME type mismatch (“text/html”) (X-Content-Type-Options: nosniff).

The main problem I have been already these last days looking at but I have not found solutions to test. I have tried changing protocol, doing it via NodePort and nothing. If you could give me some solutions to this I would be amazing. I have already assembled the cluster and the application ready to mount the pipeline with the Runner but I need to fix this aesthetic failure.

This is my ingress configuration (with a tls wildcard signed by a CA with IONOS):

If someone could solve something for me, I would appreciate it in the best way. 🙂
