Plex starting then stopping

Hello everyone,

I have a couple of questions regarding some errors I am seeing the Plex logs. For the last week a few of my friends have been experiencing an issue streaming my media from my server. I’ve been experiencing the same issue as well, but not nearly as often as them.

  1. Plex update fully
  2. Cleared Plex cache

When this started to happen I updated Plex and rebooted my PMS and it seemed to resolve it for a few days. I’ve done a packet capture and I don’t see any dropped packets. So, I pulled the logs and here is what I see:

**Nov 13, 2016 20:32:29.987 WARN [Plex for Xbox One] [Companion] Poll failed to Plex Server; testing all connections

I think Xbox One falling back on insecure is normal, but what I am wondering is the poll error. Any ideas? Thoughts?

Just to note: PS4. Xbox One, TV, and Web are having issues.

Additionally, I checked my event logs and I saw my NIC was dropping connections. I replaced the cable to see if that was contributing to the issue of the starting/stopping.

Nov 13, 2016 21:19:10.353 WARN LongPoll: Got error, closing.

does anyone have any insight on this error above? I got this error after I swapped cables on the server.
