PS3netsrv in Docker Failing

[MissionAborted]

I've tried to access my PS3 backups on my TNAS using the guide in the TerraMaster forums (How to Install PS3netsrv in Docker.) I've followed the guide exactly, but webMAN MOD will not grab from the TNAS. Nothing is listed once I follow the guide, refresh, restart etc.

Any help to get this working would be greatly appreciated. I am running the following:

TNAS: F4-210
TOS: 4.2.41
Docker: 17.05.6 with Shawly PS3netsrv
PS3 Firmware: HFW 4.90 with PS3 HEN 4.90
webMAN MOD 1.47.45
