Forge v1.10.1 — "No API found" and "Connection errored out" on all UI elements

Nobody has claimed this yet.

Hi, I have Forge running and launching successfully but the UI is completely non-functional. Every field shows an error bubble saying "Error: No API found" and any action including Generate gives "Connection errored out."

System:
Windows 11
NVIDIA RTX A3000 12GB VRAM
Python 3.10.6
Forge version: f2.0.1v1.10.1

Current package versions:
gradio 4.40.0
pydantic 2.9.2
fastapi 0.115.0
numpy 1.26.2

What I see in the browser:
The UI loads, all tabs are visible, but every field has an error bubble and nothing responds.

Command line shows:
Running on local URL: http://0.0.0.0:7860
No Python errors after launch, but browser shows connection errors on everything.
Launch flag: --listen

Has anyone seen this and found a working package combination? Happy to share full logs if needed.

Thanks,

Start by reproducing the issue with Forge v2.0.1v1.10.1, Python 3.10.6, the listed package versions, and the --listen launch flag at the local URL. Inspect the browser errors and full launch logs to identify why UI actions cannot reach the API; done means the UI fields and Generate action work without connection errors.
