Zoneminder stream

As a camera in a front end gives this “wow factor” decided to add one.
I have several cameras which are connected to the zoneminder. What i did - went to the zoneminder monitor window. Tight click. Copy url and paste it to the config. I have tried with generic - with no success. But mjpgeg seems to work fine in the configuration below

camera:
  - platform: mjpeg
    mjpeg_url: http://zoneminder/cgi-bin-zm/nph-zms?mode=jpeg&scale=33&maxfps=30&buffer=1000&monitor=1&connkey=some_numbers&rand=some_numbers

The only problem - i get a lot of errors in the logs and wonder if this can be fixed

I had a lot of these errors in my generic MJPEG cameras and stopped getting them after I specified the authentication method; even though my URL had basic authentication in it. I had to specify the method AND include the username and password, despite those already being a part of the URL. It may help. (Your authentication method may be different from mine, so please check first before copying my setup.)

 platform: mjpeg
  mjpeg_url: !secret cam3_url
  authentication: digest
  name: rear facing controllable
  username: !secret cam_user
  password: !secret cam_password

The problem is i don’t have any auth method set. It’s http and fully open
