Wanswiew mjpeg doesn't work?

Configuration
1

Hello

I had rtsp running via ffmpeg but it was a huge resource hog and it crashed frequently and I found one of my IP cams uses MJPEG. The link works perfectly in a browser but not HA. Any idea please?

camera:
  - platform: mjpeg
    mjpeg_url: http://192.168.0.201:8155/mjpeg/stream.cgi?chn=1
    name: Garage

another mjepg camera works a treat and I don’t have any authentication.

Cheers
Mark
