Sounds like this has nothing to do with haproxy, but is caused by other, intermediate devices. Just because you configure haproxy with a timeout of 1 hour does not mean your firewall or NAT device use a 1 hour timeout for SSH traffic.


when i try to connect direct on proxy or on real server i don’t have this timeout. i try to configure 2nd haproxy on dif server but i have the same issue. any idea how i can found what is wrong. after 1min is timeout if is on idle. if i use it is ok


Could be outgoing firewall rules on your haproxy instance then, or firewalling between the instance and the destination servers.

You can check haproxy logs, but it won’t change the fact that the haproxy timeouts are set to 1 hour.
