Sorry, I don’t have the exact message. I had never seen this before, but the message was contained in a narrow colored bar across the width of the upper pane of the GlassWire UI, at the top, right below the tab buttons. I wish I had thought to take a screenshot, before I closed the program out, but this occurred before my first cup of coffee and upon first boot-up of the day, and I was just trying to get online.
Recently I have been monitoring my net connections immediately post boot. I had updated to Windows 10 1809 earlier this month, and was just checking for any new connections.
It was clearly not a Windows pop-up dialogue, or a dialog window from another app, as it was fully integrated into the GlassWire Pro UI (v2.1.152), running on Windows 10 Pro 1809.
The essence of the message was that the firewall had been locked or blocked. And I had not clicked on anything in GlassWire yet to cause this, as I saw the message just as I opened the GlassWire UI.
Could this GlassWire message have been generated by some action taken by the Windows Firewall? After I exited the GlassWire UI, and stopped the GlassWire service, I still had no net access. I had to disable the Windows firewall to get online.
Recovery consisted of:
Reset the Windows firewall to defaults.
Re-installed GlassWire with the reset and clean install options.
Everything seems to be running OK now, but it is a puzzle why this happened.
The only other thing that I did prior to this event, was that I used Windows Date and Time to re-synchronize the system time via internet. It moved the time back by (-)4 hours, as the time setting was reflecting UTC from the UEFI/BIOS, and not my local time.
