"Host has left the game" message when other people try to join a game I host

[gregk-git]

I experienced... hosting a custom game but nobody could connect. Other people could see my game, and could try to connect, but got the message "Host has left the game".

how to reproduce try connecting to a custom game when I host.

I expected... that other people would be able to join my game.

Where the bug is / What should be done
I believe it's not a firewall issue, as the issue persists even with my firewall off.

Failed to ping faforever.com is really the only interesting thing in the logs I found.

Maybe network blocks ICMP otherwise no clue how we could help u. Really high chances that this is not client related....

Best thing to do is ruling out issue.

• Try on another PC in the same network. If it does not work, probably down to network set up.

Likely caused by end user network configuration
