I've recently installed FH last night and ran around with no issues.
I foudn the Eastern Pass tunnel and discovered that I get an error that fails to connect.
I've done the following:
Checked for particles
Checked my internet connection(I don't have any other issues playing games and I'm on wi-fi and steadily can do/play anything)
Checked to see if the game is blocked by firewall.
Graphic drivers are up-to-date.
Closed out other applications that may interfere.
I do not have any mods or anything else installed, just the base game(for now).
Kinda running out of solutions here and wondering if I just need to do a quick re-installation of the file.
