HI Andreas,
thanks for your replay, i have checked connection number for the last 3 mouths and maximum number of connection was 300, so i can reduce this is it's cousin the issue.
during this error server was 99% idle, the only thing is that there was a pg_dump running on one of the DB, can this cause this error, also i have restarted pg server 2 days before because of server cert update.

you can increase authentication_timeout, default is 1 minute. How many
clients do you have, do you really needs 1000 connections? If yes,
please consider a connection pooler like pgbouncer.
