Hi @sab20 ,
By the error message you provided, it appears that you are trying to make a MySQL remote connection. Before connecting to MySQL, you will need to do some configuration to ensure that the remote connection is successful.
First, you need to Edit the MySQL Configuration File:
Open the mysqld.cnf file, usually located at /etc/mysql/mysql.conf.d/mysqld.cnf. Find the line that starts with bind-address and change its value from
bind-address = 127.0.0.1
to
bind-address = 0.0.0.0
or simply comment out this line
#bind-address = 127.0.0.1
to allow connections from any IP address.
Then restart MySQL:
sudo systemctl restart mysql
Then you also need Grant Remote Access to MySQL User:
GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
Finally, Configure Firewall. Ensure that your firewall allows traffic on MySQL’s default port (3306).
sudo ufw allow 3306
