Can't play HEVC files on my Sony Bravia KDL-46EX720



I have a bit of a problem with playing HEVC files over DLNA on my TV.
Whenever I try to play it, it just tries to load it for around a minute, and then says that "The server is unavailable, try again later".
In the Plex status page, it pops up as playing for a minute, saying it's transcoding HEVC to H264.

I am using the Sony Bravia 2011 Pierre profile (since the official Plex profile doesn't work for me, it just shows a black screen with no audio). I have also attached logs.
