tmux session time :

You got halfway through your post before revealing that the issue is SSH timeout. On the server, edit /etc/ssh/sshd_config, check or add these settings:

ClientAliveInterval 120
ClientAliveCountMax 720

In this example the timeout duration in seconds is the product of the two numbers (86,400 seconds or 24 hours). Change the second number to increase the total time.

After changing the settings:

$ sudo systemctl restart ssh

sudo vim /etc/ssh/sshd_config

ClientAliveInterval 3600

ClientAliveMaxCount 3

sudo systemctl reload sshd

Timeout value = ClientAliveInterval * ClientAliveCountMax
