Today I was talking to my friends as usual on our TS, than I had to install an update for my graphics card to run BF1.
After restarting my PC I tried to connect to my TS but I couldn't.
This is what showing up:

Trying to resolve hostname ts3.cancertown.me
Failed to resolve hostname 'ts3.cancertown.me'

After searching for a solution for about an hour or so everything I tried didn't work.
FULL IP: ts3.cancertown.me:10277
