okay I'm going to put it on a thumb drive and try it thereyes...
this is little older (last 6 digits are date in YYMMDD format) firmware version, but very well tested by forum members...
Your cam is connected to NVR - so it is hidden after NVR (which works like second router) - so You can't simply connect to it from Your network because it doesn't have any IP address in it (it works in separate ip network)..
NVR offers web redirection - but this is only for camera web interface.
As I described above - firmware update - You can try doit from NVR interface...
What exactly version of firmware You have now on camera?
If the 0% problem will happen regardless of the method used, then firmware is wrong (dahua cams/NVR have protections that block the upload of the wrong firmware) or this is another symptom of problems with the Ethernet port on the camera.
this is the info on the update page:
System Version:3.120.0000000.21.RBuild Date:2023-04-18
BTW when stuck at 0% the camera was working, not hung-up
