I’m facing the same problems mentioned here. Running 3 node cluster on Digital Ocean. Running CentOS 7.5 droplet as the base OS, and installed the latest Kubernetes (1.12.0)
Everything was working fine until I rebooted the server/droplet. Then the ‘connection error’ mesg appeared. Tried the ‘swapoff -a’ and the ‘strace’ command. Didn’t work for me.
Any help/suggestion is very much appreciated.
Thanks!
