OK, so somehow I did something stupid last night, well actually a mouse problem caused it LOL.
I was looking at the Windows Firewall settings and confirming nothing changed during a Windows update and seeing if anything I could tighten up.
Somehow when using the mouse wheel, it caught on restore to default and acted like I selected it and all my firewall settings restored to default.
Apparently when that happens, it also knocks out Remote Desktop, UI3, and the app.
So I run a cable to a TV to get back in to re-allow remote desktop.
I went in and added
Blue Iris back to the firewall rules, but I still cannot get UI3 or the app to open. UI3 works on the BI computer, but not the other computers on that network.
I can disable the firewall for the Private Network (while still keeping it for Domain and Public Networks), but it gives me warnings and I assume I wouldn't want to run that way.
What setting am I obviously missing that is preventing me access to UI3 with the firewall active?
