"Something Went Wrong" on android phone

Installation Issues
1

Hello,

I just deployed Passbolt on my homelab, and everything seems to be working correctly, although I haven’t set up an SMTP server yet, so email notifications are disabled.

The issue arises when I try to connect my phone. The QR code scans without any problem, but when I enter my passphrase, I get a “Something went wrong” error.

From the research I’ve done on the forums, it seems a similar issue was fixed and was related to a self-signed certificate used by Docker.

In my setup, I have my own domain and use Nginx as a reverse proxy to handle the SSL certificate.

Could I have your advice on this issue? For better clarification, here are my docker-compose.yml and nginx.nix configurations.

docker-compose-ce.yaml :

services:
  db:
    image: mariadb:10.11
    restart: unless-stopped
    environment:
      MYSQL_RANDOM_ROOT_PASSWORD: "true"
      MYSQL_DATABASE: "passbolt"
      MYSQL_USER: "passbolt"
      MYSQL_PASSWORD: "P4ssb0lt"
    volumes:
      - database_volume:/var/lib/mysql

  passbolt:
    image: passbolt/passbolt:latest-ce
    restart: unless-stopped
    depends_on:
      - db
    environment:
      APP_FULL_BASE_URL: "https://passbolt.my.domain"
      DATASOURCES_DEFAULT_HOST: "db"
      DATASOURCES_DEFAULT_USERNAME: "passbolt"
      DATASOURCES_DEFAULT_PASSWORD: "P4ssb0lt"
      DATASOURCES_DEFAULT_DATABASE: "passbolt"
    volumes:
      - gpg_volume:/etc/passbolt/gpg
      - jwt_volume:/etc/passbolt/jwt
    command:
      [
        "/usr/bin/wait-for.sh",
        "-t",
        "0",
        "db:3306",
        "--",
        "/docker-entrypoint.sh",
      ]
    ports:
      - "127.0.0.1:8080:80"

volumes:
  database_volume:
