Need to start stream twice before play

Hello
I have a xpenology with pms and its been working for a long time with out issues
But at some update or maybe a setting ago i now need to start a stream twice.
What happens is. I start a movie/tv show the stream stops within the first second and does not continue.
I can then push back and restart the same stream and then it plays to the end.

I have search for others to have same issue, but cant seem to find anything.
This happens on android tv plex app, i cant recollect this to happen on my ipads, rasplex also have this issue.

If this happens only with specific player(s) like Android, it’s not a Synology / server issue. We can’t be of any help here.
