Can't play some files while it does before

Hi

Since sunday rasplex is not able to read some of my files while it worked before and for 8 months.
I played a tv series episode saturday evening, and sunday evening the next one didn’t play (file not found, please check directory is mounted). I tryed to play last seen episode and same behavior while it played 24hours later.
I didn’t make any update since 3-4 months on my plex server (v1.4.2) and I installed last stable openpht (1.8?) release 3 weeks ago.

My server is running on debian stable, and I didn’t perform system updates. I check file rights and all is correct.
I tryed to play those not playable files on other devices (android tablet, android smartphone and plexmediaplayer linux application) and I have no problem.
I checked logs on my server and except those recurrent errors i got nothing:
122 Jun 05, 2017 17:47:19.837 [0xa8ffeb70] ERROR - Error issuing curl_easy_perform(handle): 52

I installed official plexmediaplayer embedded on the same raspi (change sdcard) and it works well but i prefer rasplex for now (dashboard is too heavy on plexmediaplayer and i can’t have audio both on jack and hdmi).

I installed tonight the latest stable server version (1.5.6-3790) and i got the same problem.

Any ideas are welcome… i’m really confused :neutral:

Thank you

see if they work in plexweb at same time it doesnt work in openpht. if it doesnt work in plexweb, nothing to do with openpht, PMS/system issue

I just check it and it plays fine on https://app.plex.tv/web/ (with transcoding) while it doesn’t on rasplex.
My raspi is connected on the same server network by ethernet not wifi, so it maybe not a network issue.
I enable logs in rasplex but how can i get them ?

I don’t know what happened (I really did nothing) but I reinstalled rasplex on the same sdcard (class 10) and it works well …
