HA - RKE - tls: bad certificate

I installed HA over rke with self signed cert and everything was working great for couple months.
Today I tried to add one more node to master cluster with “rke up --update-only” command and it throws me error “remote error: tls: bad certificate”
Everything is healthy and working just cant add new node which is right now crucial for me.
I checked for other topics with same issues but didnt helped me.
Any tips or workaround to add one more node at least?

Rancher version: 2.2.2
RKE version: 0.2.2

Are you trying to add another controller/etc node, or just a worker? The “rke up --update-only” command only works for adding worker nodes.

Can you paste the entire command output? Does it work with normal “rke up”?
