Strange. Have you used any other firewall software lately or in the past? If so it can conflict with ours, so perhaps that is what happened.
I can suggest a clean reset of our firewall if you’d like to try it?
Before doing so though, if you switch our firewall to “Off” does the game still have issues? If so it may not be related to GlassWire at all.
CLEAN FIREWALL RESET INSTRUCTIONS
Go to add/remove programs and uninstall GlassWire.
REBOOT - Please don’t forget this step.
Remove any other firewall apps if you don’t need them. If you want to keep them, then keep our firewall set to “Off” and never turn it on and only use that other firewall for blocking.
Go to the Windows Firewall control panel and choose “restore defaults”.
Install our latest version and check “reset firewall”.
