Cannot play mkv files anymore??

Hi guys

I need a bit of a help. I remember that when serviio was 0.90 or something, my TV could play mkv files without any problem but now it doesnt seem to be the case. I dont know what I have done wrong (I've updated ffmpeg version?) or something but none of the previously mkv can be played. The profile is selected as KDL-40CX523 which is the TV.

I can play mp4 without any issues.

Could someone help please?
Thanks

The error I get is Temporarily cannot access the server. Please retry.

There's been some changes to some of the transcoding profiles. Don't know if the one you were using changed, or perhaps Serviio is selecting the wrong profile. I'd experiment with a different profile first.
