So I've been having some annoying trouble with my Ubuntu VPS. My ssh connection gets dropped seemingly randomly. Sometimes its alive for hours, sometimes it will get dropped 3 times in 30 seconds.

I've set in /etc/ssh/sshd_config:

ClientAliveInterval 120
ClientAliveCountMax 720

And on the client in ~/.ssh/config I set:

ClientAliveInterval 120
ClientAliveCountMax 720
ServerAliveInterval 120

Below is the log, the connection reset statement at the end is what always signifies a disconnect. I cannot see anything particularly critical in the lines above it, but im no pro either. Maybe something stands out to you guys?

I've set the debug level to debug3 btw as you can see to hopefully get as much info as possible :)
