Nginx conf

server {
    listen 80;

    # Redirect all HTTP requests to HTTPS
    location / {
        return 301 https://$host$request_uri;
    }

    ssl_protocols TLSv1.2 TLSv1.3;

    # Mailpit block location
    location /mailbox/ {

        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;

    }

    location ~ \.php$ {
        include fastcgi_params;

}

Docker-compose

services:
    mailpit:
        image: axllent/mailpit:latest
        restart: unless-stopped
        tty: true
        ports:
            - ${DC_MAILPIT_PORT}:1025
            - ${DC_MAILPIT_INBOX_PORT}:8025

when access to https://mydomain.com/mailbox, its show blank page
asset https://mydomain.com/dist/app.css instead https://mydomain.com/mailbox/dist/app.css

When I try add environment "MP_WEBROOT: /mailbox/" and restart nginx, page show "page not found"
I try open asset, and URL become https://mydomain.com/mailbox/mailbox/dist/app.css

I think you're trying to mix two things here. Note the following is untested, but I'm fairly confident it should work: You want https://${SERVER_DOMAIN}/mailbox/ to return Mailpit, so rather than rewriting anything, set proxy_pass https://mailpit:8025/mailbox/; and remove the rewrite rule, and finally tell Mailpit that you are using the /mailbox/ webroot by setting the MP_WEBROOT: /mailbox/.
