Question / Help problems with buffering while streaming

[Kuusla]

Hey guys,
im a fresh streamer in twitch and have some minor problems. One of them would be that some of my viewers always get the buffering screen and dont even get past this buffering thing. And then some viewers dont have any problems at all. My question now is why do I have problems like that?

My Upload is nearly 6MB but I always heard that I have to set the bitrate at max 2500 so I was always changing between 2000 and 2500. If someone could help me fix this problem, I would be very grateful.

As I said, I would really appreciate any help from anyone and hope someone has any idea what to do.
regards~

Your OBS logs are clean, so this looks like a problem with the individual viewers' internet connections just not being fast enough. You can help them out by lowering your stream bitrate, but if you feel like you need to go below 2000kbps, then you'll probably want to decrease your stream resolution as well (maybe 540p or 616p instead of 720p).
