Recording to URL fails to start on Windows

I want to set up our church PC to stream to Facebook and YouTube using streaming for YouTube and using recording to send the stream to Facebook. I have tried this on a Linux PC at home and it seems to work fine. But when I set up the same recording settings on a Windows 10 PC (I have tried this on two separate PCs) things don't work right. When I press the Start Recording button (not trying to stream to YouTube at the same time, just to Facebook) the button highlights, but nothing happens (the text doesn't change to Stop Recording, the recording light doesn't come on and no streaming takes place). If I then click the Start Recording button again, then the infamous
Capture.PNG

dialog pops up. The log file doesn't even show that recording was started. Here is the log from carrying out the steps just mentioned:

As I mentioned, I see similar results on two separate Windows 10 PCs, but it works fine on my Linux PC at home. I would really appreciate any help anyone could provide in getting this working.

Look in Windows' Firewall settings and check if OBS is allowed. It can often happen that you set your network as Public on accident (By selecting no, when Windows asks you if you want to be visible to other computers), so if the firewall asks if you want to allow OBS, and you only tick Home, it could not work. This guide seems fine to me: https://pureinfotech.com/allow-apps-firewall-windows-10/

Thanks for the suggestion, Fierelier, but my firewall was already set up to allow OBS. (And to verify this I even turned the firewall off briefly, and got the same results.)
