In order for Twitch to know who is streaming to them , you need to configure your stream key in your streaming software. Your stream key is extremely sensitive, so please make sure that you never show it on stream or in a recording. If you stream key accidententily gets revealed, immediately log into twitch and reset your key.
You will notice that when you changed your stream settings to custom, your OBS no longer shows the Twitch Chat or Stream Info Panels. In OBS these panels are called Docks, and you can add them back in quite easily by follow these steps.
Now that you have swapped over to the Ingest Relay, you should be able to increase your stream bitrate to further increase your quality. The maximum bitrate allowed by Twitch at the moment is 6000kbs for Affiliates, and 3500 for non Affiliates. I would not suggest increasing your bitrate about 50% of your available upload bandwidth.
You can play around with the other settings, but make sure you know what they do before you change them.
