Transferring to helm/charts as this appears to be a chart-specific issue, not that of helm. I'd suggest reaching out to the Jenkins folks and ask them directly; this appears to be an application level problem and they'd know best.

👍 This is not working for me as well.

Go also to http://localhost:8080/log/all, I saw :

i managed to search for the solution. in short -
configure the jenkins applications (from browser) by changing kubernetes url from "https://kubernetes.default" to "https://kubernetes.default:443" and that should solve it...

@dipeshm01 Thanks for pointing out the correct answer. I had the same issue after updating our Kubernetes cluster.

@dipeshm01 I searched on it as well, and I resolved it with the same solution.
I am pretty sure you mean this reference : JENKINS-59000

Anyway, you are a good guy 🌹 as you reported the solution immediately, however I am a lazy guy I just reported now 😔
