Hi,
Using Plex 1.5.0.951 here, I can confirm the problem described in this post still applies. No subtitles displayed unless I disable Direct Play (which is not a great option).
On another post about the Windows version, RedTopper fixed a similar issue by using DNS rebinding wizardry, which is much above my level of understanding:
I also had this problem and figured out a workaround.
I checked the logs for the client and it turns out Plex for Windows only tries to receive subtitles once and then gives up. In my case it was querying 10-40-42-250.xxx.plex.direct:32400. Since my local DNS server prevents external DNS servers from returning internal IP addresses (10.x.x.x), the query was being dropped and plex fails to load the subtitles since it does not retry any additional server names.
Do you use a firewall like pfSense/opnsense? If you do, check if you can disable DNS rebind checks to allow these queries through for now.
EDIT:
Actually, if you want to leave DNS rebinding on, see the details on this page, maybe it’ll help: https://support.plex.tv/articles/206225077-how-to-use-secure-server-connections
(scroll to DNS Rebinding)
Maybe that will help fixing the bug?
Thanks
