Playing on remote doesn't work

[danfr]

I've installed the latest version of YoutubeTV today to use with two client devices (one Windows with Plex Media Player and one Linux with Firefox 58). When I play Youtube Channel's videos locally it works both on Windows and Linux BUT if I try to play it through the PMP "remote control" I have an error pop-up "Error when loading video" in Firefox (with no exploitable error logs).

So steps to reproduce:

1. Connect a PLEX Media Player on a Windows device and a Firefox PLEX client on Linux
2. Remote control the Linux Client from the Windows Client
3. Play any video in the Youtube Channel (from Subscriptions for example)

=> The video launch on remote (Linux) fails and an error pop-up rises

I need plugin's log from server, but looks like client bug.

Same problem for me. Plugin works fine locally but doesn't work on my TV set.
