How It Affects Your App
MySQL 1820 ER_MUST_CHANGE_PASSWORD indicates that the user must change their password before they can access the application. This can cause disruption to the application as the user will be unable to access the application until they have changed their password. This can lead to delays in the user being able to use the application, as well as potential frustration from the user. It is important to ensure that users are aware of the need to change their password in order to access the application.
How To Fix
1. Check the error log for the MySQL 1820 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:

3. Check the MySQL process list to see if there are any processes that are running for too long:
$ mysqladmin -u root -p processlist
4. Check the MySQL status to see if there are any issues with the server:
$ mysqladmin -u root -p status
5. Check the MySQL variables to see if there are any misconfigurations:
