Original GitHub issue: https://github.com/NginxProxyManager/nginx-proxy-manager/issues/2356

I have a big problem with NPM, every time I restart it, I lose all the data! Certificates, etc..
I am forced to configure it as soon as a reboot is done! Very annoying when you have dozens of sub-domains.

I'm not sure I'm losing anything, but I have the impression that NPM can't mount the data directly from the docker managed volume.

Has anyone had this problem before ? I can't find anything on the internet about it.
Once I reconfigured NPM, the other applications work fine.

Can you help me please ?

I am using a docker-compose.yml:

version: "3"
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
    container_name: nginx-proxy-manager
    network_mode: "host"
    environment:
      DB_MYSQL_HOST: "10.0.1.98"
      DB_MYSQL_PORT: 3306
      DB_MYSQL_USER: "npm"
      DB_MYSQL_PASSWORD: "npm"
      DB_MYSQL_NAME: "npm"
      # Uncomment this if IPv6 is not enabled on your host
      # DISABLE_IPV6: 'true'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt

Then with directories data and letsencrypt in the same folder as the docker-compose.yml, this preserves the config between container rebuilds.
