Can't connect to Ubuntu 17.10

Two days ago i upgraded my NAS from Ubuntu 17.04 to 17.10, and since then i'm unable to connect to the machine running it. I'm on Windows 10, and i need to connect to my NAS through TV because i don't have any monitor. Both machines runs TV 13. When i start TV on my desktop it says "Ready to connect (secure connections)", but when i try to connect with the NAS it says "Connecting" and doesn't do anything else until i close the program.

I'm sure that on the NAS everything works because i checked with putty, so i can't figure out what the problem is
