SnipeIT Uploads issue

Having a weird issue with the SnipeIT container. While the ability to upload branding images and asset images/docs works (they are uploaded correctly to the server). It seems the container cannot read back the uploads. No assets images appear in the branding locations and images/docs uploaded to assets show broken. I am using a standard docker-compose file with bind mounts. PID and GUID both set to 1000.

Have tried running the recipe both as root and as standard ubuntu users, no dice.
Tried running the recipe in various folder locations, no dice.

Anyone have any ideas?
