video stops playing after few minutes over network on smart tv

I have a toshiba smart tv with android installed.
I have a shared folder on a windows 10 computer shared over SMB (I think it’s SMB2?)

My videos were playing fine over the network on VLC for ages, until awhile back I watched something on a USB stick and ever since playing videos over a network stops playing (in both VLC and nova video) and I have to goto the file and start it again.

I got a bunch of log files from VLC on the TV when this was happening (about once every 5-10 minutes)

looks like the most persistent errors given are

E/NdkMediaCodec(31359): sf error code: -13
E/NdkMediaCodec(31359): sf error code: -38

but there’s a number of things going on here are the error codes and warnings from the logs pasted here:

I have no idea how to fix this, the VLC android forums aren’t very helpful. any ideas?
