Segmentation Fault on Ubuntu #78

Closed travcunn closed 5 years ago

After the main menu, I get a segmentation fault on Ubuntu. Other times when I do it, I get the following error:

Traceback (most recent call last):

I got this problem when I was starting a server too, it seems that socket.gethostbyname_ex(socket.gethostname())[2]only contains "127.0.0.1" on Ubuntu. But if you play singleplayer game it will directly connect to 127.0.0.1 without any problem. I guess we should find another way to get all the ips of the host correctly.
