I'm seeing weird freezes when I'm connected to my server (Debian 11) with SSH. My typing stops getting to the server after a while, and after a minute or couple, all my key strokes are applied. So, they are buffered somewhere and applied after a while. This happens really frequently and it is difficulty to get anything done.
Very much appreciated if someone can provide any ideas why this happens and how to debug it.
When the freeze happens, I can open another SSH session to the same server and it works, until it freezes the same way. So, it is not the internet connection that is lost.
My /etc/ssh/ssh_config (/etc/ssh/ssh_config.d/ is empty)
Include /etc/ssh/ssh_config.d/*.conf Host * SendEnv LANG LC_* HashKnownHosts yes GSSAPIAuthentication yes ServerAliveInterval 100
