Issue with Seafile Docker Server WebDAV Configuration

I have set up a Seafile Docker server with Caddy and would like to use WebDAV. Below is my current Caddy configuration:

cloud.p37.nexus {
    encode gzip
    tls {
        protocols tls1.3
    }

    header {
        Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
        X-Content-Type-Options "nosniff"
        X-Frame-Options "DENY"
        X-XSS-Protection "1; mode=block"
        Referrer-Policy "no-referrer-when-downgrade"
        -Server
    }
    reverse_proxy 10.10.10.4:80
}
cloud.p37.nexus/seafhttp* {
    encode gzip
    tls {
        protocols tls1.3
    }

    header {
        Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
        X-Content-Type-Options "nosniff"
        X-Frame-Options "DENY"
        X-XSS-Protection "1; mode=block"
        Referrer-Policy "no-referrer-when-downgrade"
        -Server
    }
    uri strip_prefix seafhttp
    reverse_proxy 10.10.10.4:8082
}
cloud.p37.nexus/seafdav* {
    encode gzip
    tls {
        protocols tls1.3
    }

    header {
        Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
        X-Content-Type-Options "nosniff"
        X-Frame-Options "DENY"
        X-XSS-Protection "1; mode=block"
        Referrer-Policy "no-referrer-when-downgrade"
        -Server
    }
    uri strip_prefix seafdav
    reverse_proxy 10.10.10.4:8899
}

Additionally, I am using the following Docker configuration:


services:
  db:
    image: mariadb:latest
    container_name: seafile-mysql
    environment:
      - MYSQL_ROOT_PASSWORD=7TTFQf6zHPREMRKf6dhJKyxLE
      - MYSQL_LOG_CONSOLE=true
    volumes:
      - ./db:/var/lib/mysql
    networks:
      default:
        ipv4_address: 10.10.10.2

  memcached:
    image: memcached:latest
    container_name: seafile-memcached
    entrypoint: memcached -m 256
    networks:
      default:
        ipv4_address: 10.10.10.3

  seafile:
    image: seafileltd/seafile-mc:11.0-latest
    container_name: seafile
    volumes:
      - ./data:/shared
    environment:
      - DB_HOST=db
      - DB_ROOT_PASSWD=7TTFQf6zHPREMRKf6dhJKyxLE
      - TIME_ZONE=Europe/Berlin
      - SEAFILE_ADMIN_EMAIL=
      - SEAFILE_ADMIN_PASSWORD=
      - SEAFILE_SERVER_LETSENCRYPT=false
      - SEAFILE_SERVER_HOSTNAME=cloud.p37.nexus
    depends_on:
      - db
      - memcached
    networks:
      default:
        ipv4_address: 10.10.10.4

networks:
  default:
    name: seafile_net
    external: true

My seafdav.conf configuration is as follows:

[WEBDAV]
enabled = true
port = 8899
share_name = /seafdav
show_repo_id = true

The issue I am encountering is that when I navigate to https://cloud.p37.nexus/seafdav, I am prompted for login credentials, which are accepted successfully. However, after logging in, I only receive a 404 error, regardless of which library or folder within the library I attempt to access.

Could you please advise on what might be causing this issue or suggest a solution?

Best regards,
Malte
