Hi all, Fairly new to the NVR world. I've been using motioneye on homeassistant but wanted a dedicated nvr. Picked up a fairly cheap dahua 8 channel for the 6 cams I have. Using gDMSSplus app which works fine and pssSmart on my pc's. I sadly found out that I can only use IE to access locally directly to the server also! Now I have nginx proxy manager set up and use this to forward ports 80/443/37777 to handle the hosts internally . Also set up a new DNS name with noip and enabled that on the NVR. If I access my https://dns with firefox it lets me in but obviously the browser is not compatible so I cannot view the cams only the settings etc. But if I log in remotely with the https://dns using IE it says 'login failed' ! Odd that firefox lets my proxy login but not IE? I'm somewhat confused. Any help would be appreciated. Thanks

In the meantime time I set up a vpn tunnel and removed the port forward setting from 37777. Now I can open IE and access my NVR with the openvpn connected (phone and laptop). But still odd with the dns and proxy rejecting my login with IE but not firefox.
