Just wanted to share how I solved my 0kbps problem. I could stream some light stuff like among us, snes games, solitaire. But as soon as I wanted to stream some bigger games OBS dropped to 0 kb/s! I went to my wifi router admin settings and turned off firewall. Now I can stream on 1920x1080 60fps 6000kbs with no problems using WIFI, yes WIFI!!!. I even tried 20000kbs and OBS showed 15000-19000kbs, but as I understand twitch player works only with 6000kbs.
