This problem is now fixed with GlassWire 1.2.79 and any future GlassWire versions. To fix it download GlassWire’s latest version, then create a “glasswire.conf” file with your Notepad application.
Inside the GlassWire.conf text file created by Notepad please insert this text.
hostname_enable_nslookup = false
Please move the .conf file to C:\programdata\GlassWire\service
Reboot your PC.
Now the problem should be fixed. This .conf file disables GlassWire host lookups. For some reason NordVPN would block all network activity if GlassWire tried to do a lot of host lookups and this was the only solution we could find. We reported the problem to NordVPN.
Thanks for your patience and feedback so we could solve this problem!
