Discord.Net: Discord.net 0.9.5 + Mono - An address incompatible with the requested protocol was used

The bot works very well on my Windows machine, but when I tried to migrate it to a Linux server, it built fine, but when I start it, I get the following exception:

Crashed with exception, restarting.
