I have been running Blue Iris for about 4 years and never had a problem. I have been running Version 4.5.7.1 for months with no problem. Yesterday I wanted to upgrade to the newest version (4.6.3.0). I did a total system image with Acronis the proceeded to do the update. Now I can't access when I am outside of my home network and connected to 4G with the Android App two smart phones do the same thing. I have reinstalled the app, shut off Zonealarm and Windows Defender. When I run the remote access wizard it shows all is good. I restored the original image and everything works fine. I installed the update again and have the same problem. Any ideas? I am about ready to restore the original image and forget about it. I have 12 cameras, mostly Foscam and Amcrest. The PC is Lenovo I7 3.6 Ghz with 32 gig ram. I usually run about 8% CPU.
