Yeah I've been havinh this same problem too! Last month it was workiwo great, streamed for 4 hours almost every day and no problems. Middle of February, my OBS would start saying "Disconnected, Reconnecting" or it would say "0K/bs" after 1 hour and a half of streaming. Last night I was streaming Resident Evil Revelations, and I already knew after 1 hour and 30 mins it stopped!! It's so annoying!! I've tried everything, uninstalled obs, reset twitch key, different server, etc. Honestly have no clue what to do!!
