Truenas + stable diffusion

My truenas system is driving me nuts trying to get stable diffusion going so reaching out for help…

Setup is;
Truenas 25.04.1
CPU Ryzen 6C/12T
RAM 64GB
GPU 1660 6GB
HDD 21TB usable via Z1
SSD 250GB for OS

Apps running ok;
n8n
ollama
plex
portainer (Kokoro TTS working)
postgres

Objective:
Get Stable Diffusion (any flavour) running with open ports + API for use with n8n.

Currently stable:
N8n agents running idea generation via ollama, researching topics via serpapi, then passing to a script conversion agent then passing to Kokoro TTS.

Problem:
For past 2 weeks I have been unable to stable diffusion running as an app + custom app + portainer + custom container (inside portainer).

Solution requested:
Can anyone point me to a truenas specific implementation of stable diffusion?
