Hi All, Recently i have updated the k3s cluster version but after that i start getting below error in the logs and timeout response for the

kubectl

command so please suggest the solution to this problem ??

Unable to connect to the server: net/http: TLS handshake timeout

whenever i am getting timeout response for

kubectl

command the application exposed via ingress stop working and getting

502

response. These are the error logs from

/var/log/syslog

what version did you upgrade from and to?

From v1.19 to v1.20.11 Yes I upgraded all nodes including master and workers

both of those versions have been unsupported for quite a while. 1.20 has been end-of-life since February, and 1.20.11 isn’t even the most recent patch release in that minor. I would continue stepping through minor versions until you get up to 1.23 at the latest.

@creamy-pencil-82913 Ok Thanks, i will get back to you after the upgrade finishes.
