There is NO official Otland's Discord server and NO official Otland's server list. The Otland's Staff does not manage any Discord server or server list. Moderators or administrator of any Discord server or server lists have NO connection to the Otland's Staff. Do not get scammed!
It can be problem with your internet actually, i'm using internet from mobile phone and i have to restart the phone to get fix it. Don't ask me why i don't know xD
Works fine for me, you must check your network settings. Also, this thread is not related to Open Tibia, you should contact OVH support instead. Good luck.
My guess is that either your VPS requires a certificate rather than username/password to login, since the latter is a lot more susceptible to brute force and most VPS providers don't like the unnecessary risk. Or your ISP is blocking port 22 because too many of their customers have been caught attacking other servers over that port.
