Thanks for the reply. I tried that url as well, putting username and password in the Settings, although I'm using https, so not port 80, but 443. Still get error and no video. If I paste it into a browser I get the still image from the GDS3710.
What about the GDS3710 video settings for the streams? Mine are:
Stream1: H264, Baseline, 1920x1080, 4096kps Bitrate,30fps,CBR,I-frame 80
Stream2: H264, Baseline, 640x480, 512kps Bitrate,25fps,CBR,I-frame 80
Stream3:H264, Baseline, 320x240, 256, 20fps,CBR,I-frame 80
My Miniserver Gen1 firmware version is 13.1.11.17, and the Loxone Config version is the same.,
