Proxy can't connect to the auth server

#1

Ported from the slack support chat

Hello, I’m seeing that Proxy can’t connect to the auth server with the following errors:

/var/log/teleport debug log:
ERRO [PROC:1]    Critical service proxy.init has exited with error Get https://teleport.cluster.local/v2/configuration/name: x509: certificate signed by unknown authority, aborting. service/signals.go:149
#2

It looks like teleport proxy can’t connect to the auth server
because it has already received the certs (from an old install perhaps?)
it’s easiest to delete all proxy data in /var/lib/teleport/* and rejoin the cluster.
