How to resolve the 1045 error in mysql connection?

MySQL error code 1045 indicates access denied, usually caused by incorrect username or password. To resolve this issue, you can follow the steps below:

1. Make sure that the username and password you are using are correct. Check to see if your MySQL username and password have been entered correctly, and make sure to distinguish between uppercase and lowercase letters. If you are not sure if the password is correct, you can try resetting it.
2. Check if your MySQL server allows remote connections. In the configuration file of the MySQL server (usually my.cnf or my.ini), locate the bind-address option and set it to 0.0.0.0 or comment out the line to allow remote connections.
3. Check if your MySQL server is denying connections from the corresponding IP address. Sometimes, MySQL servers are configured with access control lists (ACL) that restrict the allowed IP addresses to connect. You can solve this issue by modifying the MySQL server’s access control lists.
4. Check your firewall settings. If you are using a firewall, make sure to allow inbound connections to the MySQL server.
5. If you are connecting to a MySQL server locally, try using 127.0.0.1 instead of localhost for the connection.

If the above steps do not resolve the issue, it may be a connection problem caused by other reasons. You can check the error log of the MySQL server for more information to help you solve the problem.
