The most important thing to note in the error message:

Access denied for user '[meu usuario]'@'192.168.1.1' (using password: YES)

This error indicates that the user in question is not allowed to access the database, this may occur for some reasons:

1. There is an error in your file . env and you must enter the correct database name, user and password in the variables DB_DATABASE, DB_USERNAME, DB_PASSWORD, respectively.
2. The user who is trying to access is not allowed to access the database remotely, using the 192.168.1.31 for connection your user uses the network to connect externally.
3. Mysql database configuration does not receive remote connections.

Create user for remote connection

CREATE USER 'novousuario'@'%' IDENTIFIED BY 'senha';
GRANT ALL PRIVILEGES ON 'seubanco'.* TO 'novousuario'@'%';
FLUSH PRIVILEGES;

Accept remote connections in Mysql (on an Ubuntu 18.04)

Edit the file mysqld.cnf

sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

Change the bind-address of:

#bind-address            = 127.0.0.1

To:

bind-address            = 0.0.0.0

Restart Mysql

sudo systemctl restart mysql
