The solution has been posted above in this thread:
To solve the issue:
-Uninstall other firewalls or ‘hardening’ tools that are most likely causing the issue.
-Uninstall GlassWire
-Go to the Windows Firewall control panel and choose “restore default”
-Reboot
-Install our latest version with “reset firewall” and “clean install” also checked (clean install will remove your history and settings, but it may also help with this issue).
The issue should not happen again. This issue is due to other tools being installed with GlassWire, or it’s possible you used an older version of GlassWire that had this issue.
You can read here GlassWire Software Version Changes List how this was solved with our February 24th update, so yes we do care. However, currently with our up to date software we cannot recreate this and we aren’t receiving any reports about this issue to our helpdesk.
When this issue happens we get bombarded by emails to our helpdesk, and posts in our forum, along with uninstall reports. We then quickly make changes to solve the issue and release an update.
