Project 1999 - Connection issue that has been driving some of us crazy

...when trying to connect to Green: every once in a while, I just can't log in to Green. After selecting the Green server from the server list, it just hangs in there for a minute then goes back to login screen (and I'm logged out...).

Logging on Blue and Red usually works fine meanwhile.

I know this has been randomly happening to a lot of people.

@Rogean:

Code:

My computer trying to connect to Green but failing to do so:

19:45:15.453690 IP 192.168.1.2.48691 > 76.24.114.31.9000: UDP, length 14

Code:

My computer trying to connect to Green and getting great success at it:

19:47:58.104374 IP 192.168.1.2.51160 > 144.121.19.168.9000: UDP, length 70

Red and Blue seem to have IP addresses also in the 144... range and they pretty much always work.
Where does this 76.xxx come from? This might be the dreaded issue.

Thank you for your attention.
