Every time that I’m trying to access nginx via localhost:8000 / 127.0.0.1:8000 I catch this error:
nginx_1 | 2022/05/29 13:28:57 [error] 32#32: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.22.0.1, server: , request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://172.22.0.5:9001", host: "localhost:8000", referrer: "http://localhost:8000/"
A day before this docker config worked
I created the github repo for the for easier code review
What I’m already tried:
- Change FPM/Nginx ports
- Restart WSL/Docker/PC
- New symfony project
- Add php && nginx containers at the same network

You are trying to use the port mapped on your host
9001
to connect to a container using its services name.You have two options:
Use the port that the container is listening on
9000
in your nginx upstream.php:9000
Forward the upstream to the host with
host.docker.internal:9001
.Bonus: use a Unix Socket, but that is a different ball game.
When services share a network and have to communicate with each other, I would usually use the "internal" port. This way, you keep the network traffic within that network. So "solution 1" would be the best approach if you are using TCP/IP to connect. Plus, if you don’t need to connect from outside the Docker network, you don’t have to map the port on your host.
So… this should work:
I had the same problem. It was only because I was using
CMD
orENTRYPOINT
; they both prevent php-fpm from working properly.
