Halo 5 forge connection error?

Trying to load up a custom game to get used to this pc fps thing but the map never gets past the loading dedicated server part then i get a timed out message and lost connection message. anyone know whats going on?

They just launched a halo game on pc for the first time in years for free, a lot of people would be wanting to try it, expect troubles with the servers…

yeah like with me its probably your firewall blocking it, turn it off and try again next time you play
