If it works fine when all the pods are on one node, but not when you have multiple nodes, it sounds like CNI traffic between nodes is blocked or dropped. Make sure you’ve got all the correct ports open.

I think i have a lead, and it's kinda code 40 and rancher not really helping me. I'll update you if i was right.
Okay. All of this happens because the nodes i used used to be rancher 1 hosts. Not sure what is really happening as removing rancher 1 agent and stopping eveyrhting didnt change anything, but installing the nodes on fresh new systems works flawlessly.

yeahhhh I would not reuse rke1 nodes unless you clean them very thoroughly first.

Not even RKE1, rancher 1 (cattle) lmao. Still in prod and works very well, way less complicated than rancher 2. Oh well.

oh wow
that is pre-Kubernetes!

Yes, and for my need it's better than kubes. Very sad it's deprecated.
I have 3 production hosts, company of 7 people. I don't need the "400 hosts in 15 minutes" capabilties of kubes
