Here is the warning message i get.
Hosting Failure:
ICO has detected that most players cannot join your game. This is usually caused by a firewall and/or router configurations. For more information on resolving this issue, please see the SINs FAQ at https://www.sinsofasolarempire.com/
I do not have a router of any kind, and i tried turning off my firewall all together but i still receive the same message. I have created a ICO account and can view the lobby, most games i attempt to join gives me a "Rejected by host" but i can join a few
The same problem applies to my friend who lives 5 minutes away from me and uses the same internet provider. When we attempt to join the others hosted game, the game waits a few seconds and is unable to connect (not the "rejected by host" message, however i forgot to write down what it said). He also turned off his firewall program and it did not help.
I have looked through the forums but it all seems to involve a router or firewall. The one that seems relevant i do not fully understand (see link below).
