Playback fails from NFS mounted WD MyCloud on Raspberry Pi

I am trying to get my WD MyCloud NAS working with my Raspberry Pi running OSMC.

Raspberry Pi is a revision B
Operating system is OSMC 2015.08-1 (kernel: Linux 4.1.5-1-osmc)
WD MyCloud has been updated to the latest firmware and any other device on my network can play the files on it. I created a file called test.mp4 that I use to test playback.

When I try to start playing a file, I get the following error in the log:

20:24:41 149.729004 T:2681205792   ERROR: ffmpeg[9FCFF420]: [mov,mp4,m4a,3gp,3g2,mj2] error reading header                                                    
20:24:41 149.729980 T:2681205792   ERROR: Open - Error, could not open file /home/osmc/mnt/WDMyCloud/Shared Videos/Movies/test.mp4
20:24:41 149.736740 T:2681205792   ERROR: OpenDemuxStream - Error creating demuxer  

I read online that this could be caused by network latency. I can copy files at around 7MB/s to and from the Pi, but I still created the following advancedsettings.xml to see if it changed anything (it didn’t):


I would appreciate any help, again the same file (test.mp4) will play just fine off the external drive. Besides mounting the external drive and NFS mount the OS is stock. Thank you for any help!
