I've turned off KasperSky for a moment, and through windows firewall allowed everything regarding OBS etc. Still ain't working.
I did notice that OBS mentioned that some plugins with OBS would not work as good as others with windows 10, but either way this wouldn't explain that other CLR browsers work.
Do you have any other ideas besides firewall and kaspersky to be checked regarding blocking it?
I've also tryed going through Twitch Alerts website today as a "test", and their links doens't show up either in my OBS.
I do also have updated everything, as well what OBS recommend.
