Question / Help Black screen after random time recording from a URL source.

Basically I started using OBS to create primitive CCTV - I'm streaming a video from phone using IP webcam and recording it with OBS (source - browser and url address)

Buuut sometimes, at various periods of time (twice it was ~20 minutes, once 1,5h.) from start of recording the screen goes black (sound is okay). The stream is also working fine, if I refresh it manually in OBS it works and records again. Is the option "Refresh Source when active" will solve this problem? What it's actually do?

I've lost important footage 2 times because of this :/
