new streamer

Hello, I followed a youtube video of steps to try to fix the error I keep receiving "Failed to connect to server" when trying to start a stream to Facebook LIVE. I have the stream key correct and I have tried numerous settings changes to try to resolve the error. Will someone please look over...

Hey Im new to streaming and I really like it but sometimes Im on discord with friends while I stream and I have push to talk so stream doesnt hear me when I talk to friends but I realized that the stream can hear them and idk how to prevent that. Is there a setting where stream hears the game...
