So I'm trying to create a server and client in Unity of my game. The server handles physics simulation, while the client is just a glorified UI. I'm using Google Cloud's free trial to create an Ubuntu server and uploaded my server, but something must be wrong: the server doesn't look like it's opening port 7777! omiyagames@---:~/v0.3$ ./everybody_plays_golf.x86_64 -batchmode -nographics -logfile log.text & omiyagames@---:~/v0.3$ sudo netstat -anp Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1681/sshd

The code is open-source, with the most relevant script being ServerManager.cs. So, anyway, I either need this fixed, or have a backup plan. Any ideas?

Edit: also, the log:
