Jenkins behind NGINX with websockets. kubernetes 1.21 on EKS

2 nodes:

Windows node - JNLP connects works fine running powershell in container and then it hangs if parallel linux container runs, Jenkins hangs and dies error 404

Linux node - JNLP connects, SH command hangs, no error appear, sometimes jenkins hangs with error and fails. Sporadic. 50% works, sometimes it passes fine.

POD not being destroyed at all if it hangs. Sometimes may appear error 500 sometimes NosuchMethodError.

The problem started appearing after adding changes needed to have windows containers, changes where made to AWS Roles.

Terminating Jenkins Job does not work - jenkins hangs until full reboot

running ubuntu container after running SH and jenkins hangs
