fastapi's Issues

Can preview app but does not work once deployed

I can preview the app, but once I deploy it, it does not work

Error: class uri 'uvicorn.workers.UvicornWorker' invalid or not found:

I had built a FastAPI Azure webapp and used your idea of passing "gunicorn -w 4 -k uvicorn.workers.UvicornWorker main:app" in startup command, but I keep getting the following error.

Error: class uri 'uvicorn.workers.UvicornWorker' invalid or not found:

I have a "requirements.txt" file like you have in your project and have included both gunicorn and unicorn libraries, but for some reason the I feel the webapp doesn't pick the gunicorn instance from the virtual environment. Have you faced anything like this?

didn't respond to HTTP pings on port: 8000

After the deployment of azure app service with fast api I got this error didn't respond to HTTP pings on port: 8000

Just wanted to say thank you :)

Awesome tutorial including Caddy 2.
Detailed and to the point, even basic like adding sources and creating services.
Thank you for sharing.
