wp-admin redirect misses a slash behind apache reverse proxy

[Apfelwurm]

Hi @ALL,
i have a weird behaviour:

My wordpress container behind an apache reverse proxy is working perfect, the same goes for all the links on the page. When i try to access https://domain.com/wp-admin i get redirected to https://domain.comwp-admin and therefore its not working.
When i access any other link from the page without a trailing slash it gets redirected like it should.
When i try to access https://domain.com/wp-admin/ it works perfectly.

All the issues i could find related to redirection errors were based on the fact that the installations were reachable in a subfolder, which is not the case here.

the compose file looks like:

version: '3.6'

services:
  db:
    image: mysql:5.7
    volumes:
      - /srv/domain/database:/var/lib/mysql
      - /srv/domain/database.sql.gz:/docker-entrypoint-initdb.d/backup.sql.gz
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: PASSWORD
      MYSQL_DATABASE: DATABASE
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: DATABASEPASSWORD

  wordpress:
    image: wordpress:latest
    depends_on:
      - db
    ports:
      - "127.0.0.1:8084:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_NAME: DATABASE
      WORDPRESS_DB_PASSWORD: DATABASEPASSWORD
    volumes:
      - /srv/domain/plugins:/var/www/html/wp-content/plugins
      - /srv/domain/themes:/var/www/html/wp-content/themes
      - /srv/domain/uploads:/var/www/html/wp-content/uploads
      - ./upload.ini:/usr/local/etc/php/conf.d/uploads.ini
  

the apache site config looks like this:

<VirtualHost *:80>
  ServerName domain.com
 Redirect / https://domain.com
</VirtualHost>
<VirtualHost *:443>
  ServerName domain.com

  ProxyPass / http://127.0.0.1:8084/
  ProxyPassReverse / http://127.0.0.1:8084/
  ProxyPreserveHost On
  ProxyAddHeaders On
  RequestHeader set X-Forwarded-Proto "https"

SSLCertificateFile /etc/letsencrypt/live/domain.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/domain.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>

can someone point me to my fail here?

Thank you!

You shouldn't need ProxyPassReverse in your configuration -- it seems like that's probably related?
