When i start streaming, everything if fine for about 30 minutes - 1 hour 30 minutes. But once i stream after those periods, the stream on twitch constantly starts buffering and sometimes disconnects me from the streaming server. i did stream test and my bitrate goes down after an hour. any explanation as to why this happens? its been going on for a couple weeks. i can only stream for an hour before this starts happening but i want to stream for longer, i also use wired internet and have a good router and modem, which provide me good upload and download speeds so i dont why this is happening.
