Playing Plex sometimes stops buffering

When i start to watch a MP4 video (direct play) on my aTV3 sometimes the buffer stops and the video stops too at the end of the buffer. When i reboot the aTV3 and open up the Trailer app again i can continue where i left off. This occur once a day maybe once every two days.

This happend when i installed a new PMS on Raspberry Pi3 because there were no new updates for my Synology DS413. The latest version on my DS413 was PMS 0.9.16.6 and i didn’t have this issue. I moved to Pi3 for the newer PMS updates but now i encounter these “buffer” problems. Anyone has an idea?

PlexConnect version ?

I get this issue now what have you done to fix this?
