i want to use docker to containerize nginx, fastapi and 2 streamlit apps. All 3 apps (fastapi, 2streamlit apps) do not interact with each other. Nginx should work as reverse-proxy for the 3 apps. For fastapi it is working. I can send rest-api requests to http://ip:80/twxservices . "twxservices" as endpoint is added in the app.py file and not in the nginxconfig.
The streamlit apps are not reachable through this http://ip:80/stream1 and http://ip:80/stream2 I get the error: 404: Not found
Thanks in advance for your help. Find below the filestructures and the config files. This is the filestructure and how the reverse-proxy should work:
