Apologies to everyone who turned up today for the session. I had thought it would have been pretty straightforward to pick up where we left off but once again ArmA plays hard to get.
After a fair bit of research and trial and error I have managed to get someone to finally find the server (5 hours later) and will test in the week if they can connect and get into the game. Many thanks to @Concord and @Vartuoosi for your help in diagnosing the issue(s) which I have narrowed down to either firewall or some additional port forwarding I've had to do for the steam client which I didn't have to do last time around.
I could not attend today. Sorry for your setbacks. Glad you're able to troubleshoot for resolution. I look forward to playing this again soon. Thanks for running these.
No worries. Thanks for setting it up and working on a fix.
Maybe we can get some more players on board with some lead time.
Looking forward to the next session with you and the other FGM guys.
