Question / Help my stream freezes every couple of seconds

[feidos]

Can anyone help me. I tried to set different settings, nothing helps, still freezes.
My system:
Windows 8.1 x64
i5 4690K
GTX 970
8GB RAM
Download: 80mb/s
Upload: 80mb/s

I tried any EU server, same problem. In attached log file i used Prague server.

Spoiler: My ping test

Spoiler: And one more Twitch test

I looked through the logs and noticed a problem

Completed handshake with rtmp://live-prg.twitch.tv/app in 954 ms.
Completed handshake with rtmp://live-prg.twitch.tv/app in 1192 ms.
Completed handshake with rtmp://live-prg.twitch.tv/app in 1188 ms.

but in ping test to Prague server i have 62ms.
Maybe someone knows what the problem is..

Just in case

One more thing, i tested ShadowPlay and XSplit, stream freezes anyway. Then i tested another streaming service with the same settings in OBS, worked perfectly. What could be wrong with Twitch in my case? Maybe i need to change some settings, have any ideas guys?
