Hi welcome, It's been a while since I stepped in. I ended up buying a Asus router and setting it up for a VPN. Then I added the NVR IP address to the app and have had no issues doing remote viewing. But note: VPN will not work on phones in data saver mode. Don't make that mistake. Lots of information here on how to set up the VPN and a lot more skilled knowledge around. I had no idea how many people would respond and help out each other when I made this post almost a year ago! Thank you to all that helped .My Q-see phone app and outside access still works after setting up a NoIP.com DDNS account...... it stopped connecting when the q-see DDNS server shut down.
