NPM don´t works with localhost

[Jamyz]

Hi!
I dont no what is wrong.
I have a Raspberry Pi 3 with NPM in Docker.
My Pi3 as ip 192.168.1.10.
Docker nginxproxymanager_app_1 as IP 172.18.0.3, network is [nginxproxymanager_default].
Docker nginxproxymanager_db_1 as IP 172.18.0.2, network is [nginxproxymanager_default].
I have in config.json :
{ "database": { "engine": "mysql", "host": "db", "name": "npm", "user": "npm", "password": "npm", "port": 3306 }, "jwt": { "key": "-----BEGIN RSA PRIVATE KEY-----\n\n-----END RSA PRIVATE KEY-----", "pub": "-----BEGIN PUBLIC KEY-----\n\n-----END PUBLIC KEY-----" } }
and docker-compose.yml
version: '3' services: app: image: 'jc21/nginx-proxy-manager:latest' ports: - '80:80' - '81:81' - '443:443' volumes: - ./config.json:/app/config/production.json - ./data:/data - ./letsencrypt:/etc/letsencrypt db: image: 'yobasystems/alpine-mariadb:latest' environment: MYSQL_ROOT_PASSWORD: 'npm' MYSQL_DATABASE: 'npm' MYSQL_USER: 'npm' MYSQL_PASSWORD: 'npm' volumes: - ./data/mysql:/var/lib/mysql
I create various host with certificates like :
hub.domain.com -> 192.168.1.11:80
nas.domain.com -> 192.168.1.111:5000
router.domain.com -> 192.168.1.1:8443

All works, but when i try something like npm.domain.com -> 192.168.1.10:81 doesn´t works. I dont have access.
Why is wrong ?
