🛠 Troubleshooting

Nothing updates instantly

• Restart ComfyUI
• Hard refresh your browser (Ctrl+F5)

Protected images won’t preview

• Confirm api_key.txt exists and is formatted correctly: CIVITAI_API_KEY=...
• Restart ComfyUI

Fetch says “No items returned”

• Prefer using a post URL (/posts/<id>)
• Some content may still be restricted by your CivitAI browsing/account settings

🔐 Security notes

• Your API key stays on your machine in api_key.txt.
• The browser does not need your key.
