App/Game Name: Garry's Mod
Error Code/Message: *No servers shown in Multiplayer server browser (standard and legacy)*
Error when attempting connection to other Steam player - "Connection failed after 4 attempts"
Purchased Garry's Mod Saturday to join in on the GMod Event, but had some issues after downloading and installing the game.
Windows 7 64 bit - all drivers current
Q6600 quad core OC @ 3ghz
Verizon Fiber network 150/65
After downloading and installing, I rebooted. Opening the game was normal, but clicking Multiplayer shows a blank server window, even when using the legacy server browser. I also get a connection timeout when attempting to connect to other players via Steam during the event, same error message on all of the attempted people ("fail after 4 attempts").
Port forwarded Steam and GMod, turned off all of my antivirus/firewall software, rebooted with all programs off in msconfig (clean startup). Same issue with GMod.
Added the MasterServers files recommended by Steam support forums, rebooted, still no go. Reinstalled Steam and GMod, still no go.
I am posting this because I have tried everything I can think of and everything I can find online.
One question - I purchased the Steam Garry's Mod for $9.99. Do I still need a Source based game like Counterstrike or TF2? I did not see any notes about that, but several forum posts mentioned it. That is the only thing I haven't tried that I am aware of.
Thanks for any help in advance, couldn't find any posts on the GSN forums about this.
