web player problem - Githubissues

Hi dears
I have no problem streaming video at the android ExoPlayer and the vlc at windows. But when the video is played on web players, some of the first ts parts run properly and the next ones stay in the loading mode, and if I move the movie back or forth, it's still in the loading mode.
More details in the video below: https://youtu.be/aBi6AlIcItw
My nginx conf is similar to the following:
