Summary of the issue you are facing:

I create an album in Photos App and add photos and videos to it. In the album properties, I create a public link and share it with friends who don’t have an account on my Nextcloud. When the user opens the public link, the photos open in their browser, but the videos don’t open or play.

Steps to replicate it (hint: details matter!):

  1. create an album in Photos App and add photos and videos to it

  2. create a public link of album and share it

  3. try to open link in browser and play videos

Hi @Sergej_Pligin,

Looking at your web server log, the smoking gun is this line:

The server responds with 503 (Service Unavailable) before a single byte of video data is sent. The browser never gets the file.

Likely cause: nginx proxy timeout during large file transfers

To give you a precise answer I would need to see your nginx reverse proxy config. If you prefer not to post it, make sure at minimum that proxy_buffering is off:

proxy_buffering off;

and that proxy_read_timeout is set high enough for large files (the default is 60 seconds, which may not be sufficient for streaming a video through the proxy chain):

proxy_read_timeout 3600;

Both settings go into the server or location block in your nginx reverse proxy config that handles requests to Nextcloud.

h.t.h.

Thank you for your response! I followed your advice, but it didn’t work. I also found out that direct MP4 file share playback works, but album/public share doesn’t. I think the issue lies in the Photos/Albums layer.
