Pretty much all my cameras are using the generic driver - even my Foscams as the Foscam driver doesn’t work for me. They all use basic authentication as well and all are still working as of the latest update (.32.3) for me.
Same thing has happened to me. I’m using the ffmpeg camera to get it to work, but it doesn’t show realtime updates when I click on it, so I’d rather go back to generic. Any luck?
