Issues Opening Certain Files via WebDAV/Video Player

Nextcloud version: 15.0.2.0
Operating system and version: Ubuntu 18.04.1 LTS
Apache or nginx version: Apache/2.4.29
PHP version: 7.2.10-0ubuntu0.18.04.1

The issue you are facing:
Background first: I’m running the 40GB OVA from https://www.hanssonit.se/nextcloud-vm/ on VirtualBox. Storage is a NFS mount from a NAS to /mnt/ncdata.

The issue I’m having is that certain files fail to open over WebDAV and/or via the video player app. On Windows, the error I get is “Cannot open file for read access. The file size exceeds the limit allowed and cannot be saved.” which research suggests is a general error for something going wrong. On nextcloud’s player, the error is “The video could not be loaded, either because the server or network failed or because the format is not supported.” along with a black video player.

I thought I had noticed a pattern, that files over a certain size failed, but this does not appear to be the case with files at ~50MB failing while files up to ~1GB play properly depending on the file. However, one of the files ~2GB in size will download fine from NextCloud, despite failing over WebDAV and the video player.

While most files fail to play in both spots, some files will play properly in Nextcloud but fail over WebDAV. I have not noticed the opposite to be true.

I have confirmed that the files are intact by checking them on my NAS’ filesystem, where they play correctly checksum with the originals. This does not appear to be an NFS issue, as the files appear intact on the NextCloud VM’s mountpoint.

I’ve tried updating the Ubuntu OS, restarting the VM, updating/restarting the NAS, etc.

NFS mounted with : SERVER:PATH on /mnt/ncdata type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=IP_ADDR,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=IP_ADDR)

Is this the first time you’ve seen this error?: Yes

Steps to replicate it:

  1. Upload a video file with the web interface.
  2. Try to access the file through the web interface via “Video Player” app or via media player and WebDAV mount on Windows 10 client.

Note: Following logs have been redacted, but should still be useful.
