It happens on from time to time. We have other Jenkins master in the same project. The other master works good. 

Kubernetes plugins in: 1.16.1

Jenkins master is: Jenkins ver. 2.164.2

I added the option + restarted pod. Monitoring how it behaves. Carlos Sanchez thank you!

Good that there was a workaround, but you should not need to set an obscure system property just to make the system work. Any known way to reproduce from scratch?

I am guessing you are using some sort of time-limited authentication to the cluster. What specifically do your credentials look like? The current “fix” merely refreshes the client after a day, which is better than nothing, but not very discoverable. Possible resolutions include

  • Printing a meaningful error about an expired token somewhere that an administrator will see it (not just the system log).
  • Automatically asking to refresh the token by some means.
