I have been searching the internet for over an hour now. My OBS keeps telling me that it can not connect to the server. I have deleted it's directory from the Roaming folder, tried reinstalling.. and still nothing. Any insight would be awesome seeing as I am a first timer here and eagerly looking to start up my stream.
Have you tried generating a new streaming key from twitch.tv/broadcast? You also need to visit your dashboard here: http://www.twitch.tv/broadcast/dashboard in order to activate your channel.
OBS constantly updates, so make sure you're using the latest version from their site. If you have any questions, you can reply here, contact me on twitch (xangold) or through my skype I use for troubleshooting (twitchxangold).
