Access denied on docker container of mysql 5.7 - mysql

Question

I have a problem with mysql 5.7 container denying access to my nodeJS container. I'm using docker-compose and I'm running docker on Ubuntu 18.04 lts.
I apologize for the mistakes in English. This is not my mother language.
I replaced all confidential information with *** and in the images I put a red line
Here's my docker-compose.yml
version: '3.1'
services:
db:
container_name: '***-db'
image: mysql:5.7
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
- MYSQL_ROOT_PASSWORD=***
- MYSQL_DATABASE=***
- MYSQL_USER=***
- MYSQL_PASSWORD=***
- TZ=America/Sao_Paulo
command: mysqld --sql_mode="" --character-set-server=utf8 --collation-server=utf8_slovenian_ci --init-connect='SET NAMES UTF8;' --innodb-flush-log-at-trx-commit=0
ports:
- 3306:3306
volumes:
- ./db_data:/var/lib/mysql
network_mode: "host"
server:
image: server
restart: always
ports:
- "2000:22"
- "3000:3000"
network_mode: "host"

image: portal
restart: always

ports:

I am using a volume with the database for my mysql container. In this volume I have my user and password set and I also have my schema with every table. I copy everything from this path:
/var/lib/mysql
that I have on my configuration (I am not using docker on this one) in another computer with the same version of mysql and that I know it is working.
Here is my server Dockerfile:
FROM ubuntu:18.04
LABEL maintainer = "***"
LABEL build_date="2020-04-24"
RUN apt-get update && apt-get install -y curl
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash -
RUN apt-get update && apt-get install -y nodejs
#COPY AN CONFIGURATION OF APP
COPY ***-server /home/root/***-server
WORKDIR /home/root/***-server
RUN npm install
EXPOSE 22
EXPOSE 3000
CMD ["npm", "start"]
Here is my nodeJS file to connect with the mysql:
"use strict";
module.exports = {
config: {
connectionLimit : 200,
host: 'localhost',
user : '***',
password : '***',
database: '***'
}
}
this is the error mesage that docker compose send to me, when I try to connect:
And this is image of the container of the mysql that I am trying to access. I make access to the mysql inside the container using the same user that I am using on the server.
