I know the information I’m providing is very limited but I lost SSH connection to my Ubuntu Mate (Odroid XU4)

I tried from different host , same issue, I also have very limited torrent connection from the Odroid.

I don’t have firewall on the device, and I didn’t change anything on the network,

My router intrusion protection keep detecting a Tor replay (which I’m dropping) bot that on a different port.

I didn’t did match recently, I installed fail2ban a few days ago (not today) which can be a obvious link.

PS all package installed was made by SSH, is there a way to order PKG installed by SSH , or all PKG listed by date of installation ? I’m not to sure what to do though, how can I fix this?

UPDATE : I removed Fail2ban and the issue remain

Hi @kevincork, I’m no expert on the topic but have a quick thing to try, namely, purge fail2ban:

sudo apt purge fail2ban
