I was trying to get Plex to run in a container on CoreOS and for the life of me I couldn't get it to start. I kept getting the following error:
Error: Unable to set up server: bind: Cannot assign requested address (N5boost16exception_detail10clone_implINS0_19error_info_injectorINS_6system12system_errorEEEEE)
It turns out that at some point I had enabled IPv6 and that caused the problem.
So edit your Preferences.xml and disable IPv6 via EnableIPv6="0"
Here's my plex.service for completeness.
