Hello. Me and my friends all chat/play games over my buddy's IP. One night a few weeks ago, I suddenly wasn't able to connect to my buddy's Terraria server. Then I went to jump in Teamspeak -> couldn't connect to his address. I ran a ping test and found that I can't reach his IP anymore. I tried using another computer, nothing. I bypassed my router, nothing. Please, can anyone shed some intelligence my way? Thank you.
