Hi, I was hosting a game room (for the game HaxBall. com) on VPS SSD 1 for almost 2 months now with any bigger troubles (not counting ddos attacks) but recently something went wrong. I had lags on the room so I decided to restart the game room and see if it would help. I connected with the VPS via desktop connection, restarted the room in the browser and then I tried to connect with my room on the game but I couldn't. No one could. It fails to connect with the room every time. When I visit this site: https://www.haxball.com/webrtcdiagnostics from my VPS it shows me that no srflx candidates were found, but it has to be "YES". On the same site is written: "If no srflx or host candidates are found then it's possible that webrtc is being blocked by your browser, in this case try disabling extensions or try running this test with a different browser." I disabled the one plugin I had installed on the Firefox on VPS but it didn't help. I also installed Google chrome on the VPS but the same result. I restarted the VPS but nothing changed, I even bought a second VPS (SSD2) but still "Srflx candidates found: NO" and can't connect to my room. Please help.
Edit: the only extension i had installed on firefox was:
