Idk about other players but twitch is one of the main reasons i still play the game. Typing in any twitch username to try and connect always gives the error INVALID OAUTH TOKEN. ERROR: UNAUTHORIZED: ERROR CODE 401
I have seen aqshy posting on reddit saying that its been fixed but its not.
Hey, I tried it right now and it works. 
I am on Playstation. Hope it will work for you too. 
This almost sounds like an oauth issue than it does a client issue. Maybe get a new oauth token and input into whatever you’re streaming through? To get check your oath token check Dashboard → Settings → Stream and then “Primary Stream key”. You could also just try logging off and in again and that might just reissue your oauth token as well
