ONVIF Camera Questions

Hello Everyone! I have been reading other topics about ONVIF camera errors, but mine don’t seem identical. I have validated the camera with VLC on windows, then also on FFMPEG via command line on the raspberry. I didn’t get any issues with ffmpeg there, but the error below shows on reboot of HA.

It’s latest version, running on a VENV. Share any ideas you have to fix this, I will also continue to tinker
