Hi everyone,
I'm having an issue with the private / public networks for my fastAPI app.
I've read your docs and tried to get internal docs working.
To do this, I've set the start command to --host :: (and that worked perfectly for the internal link).
But then the host is set to :: the public domain won't work.
And if the start command is set to --host 0.0.0.0 then the internal link won't work.
How do I get both up and running at the same time?

I did.
Just figured out the issue!
In the end it turned out that the issue was with using uvicorn.
It looks like uvicorn can't bind to both ipv4 and v6.
So I ended up setting up gunicorn to start my fastAPI app.

All good Brody - but any idea why this might be happening?

Have you checked if the public domain is pointing to the correct port under Settings - Public Networking ?
