Is this the default installation or are you using a custom domain via NGINX (possibly with a reverse proxy in front of it?).
In any case, NGINX logs would be good to have!
docker-compose logs -f then try to access the site and post the logs displayed

The Mailcow is behind a traefik. this stop working with the April update.

I already checked and modified the mail-nginx proxy buffers values, but I still can’t get it to work.

I found the workaround to solve this issue

i create a middleware on Traefik, dynamic file

http:
middlewares:
limit:
buffering:
maxRequestBodyBytes: 2000000

then call on the docker-compose.overrride.yml

  labels:
    - traefik.http.routers.**moo**.middlewares=limit@file
