Docke 502 Bad Gateway nginx (Mac)

I'm trying to work out whats causing a 502. When I run docker-compose up, it shows 502 Bad Gateway. Why is that?

in the docker logs write: 2022/01/03 18:35:13 [error] 115#115: *7 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 172.18.0.5, server: _, request: "GET /typo3/install.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "retro.vm52.iveins.de"
