Need help with setting up 9router in Cursor custom models;

[wojciechsacewicz]

Hi! I've tried following the Cursor IDE setup guide, but to no avail.
I keep hitting this error:

Request failed with status code 400: {"error":{"type":"client","reason":"ssrf_blocked","message":"connection to private IP is blocked","retryable":false}}

I am calling custom models like ag/gemini-3.1-pro-low or cx/gpt-5.4. MITM is up and running via admin privs.
Yes, i've logged into those providers mentioned above.

OS: windows 11

Help would be appreciated! :)

Turns out i NEEDED to use tailscale or any tunnel to make the proxy 'public' cuz cursor connects from their servers not from my machine, solved.
