Randomly couldn't connect to my VPS, it was working literally hours ago, and I haven't done anything out of the ordinary. What would be the most likely problem?
Edit: I do remember accidentally doing
sudo chmod -R 777 /var/. According to the second answer on ssh_exchange_identification: Connection closed by remote host /var/log/btmp should be 600, but I do not have btmp in my /var/log dir
