I have several of the cameras you have in your signature line and they all work as intended.
I suspect that at some point you went in somewhere and unchecked something thinking it would make the camera more secure.
People usually go into this area and start unchecking stuff without realizing what it does:
And sometimes it just gets wonky with an ONVIF password conflict.
At some point you either changed the ADMIN password or it didn't carry over to the ONVIF password at initialization or you created a new user and it didn't carry over.
Go into the camera GUI and there is a tab under one of the options where you create users and passwords and there is a tab for ONVIF user. Go to that tab and make the admin password what you want it to be and hopefully that fixes it. Or if you are using another username, make sure it is under ONVIF user.
