Reverse proxy serving API - Invalid HTTP request

[Jean-Baptiste_Herold]

1. The problem I’m having:

I m trying to serve an API over HTTPS with reverse proxy Caddy
Seems that Https is ok since I can access api on the web but on api side “Invalid HTTP request” is showing.
Uvicorn is running the api that is build with Python and FastApi.

how to send correct http query from reverse proxy to api so it is read and processed by the api?

2. Error messages and/or full log output:
