The final answer is: There is no unique solution for this problem. However, some common solutions include:

• Defining a public or private variable to hold the database connection
• Initializing the connection in the constructor
• Reducing the number of connections by reusing existing connections
• Increasing the timeout values (e.g. wait_timeout)
• Updating the MySQL configuration file (my.cnf or mysql.ini) to improve performance

It’s also recommended to check the following:

• Operating System proxy settings, firewalls, and anti-virus programs
• The Firewall or Anti-virus software isn’t blocking MySQL service
• Stop iptables temporarily on linux
• Stop anti-virus software on Windows
• Check the query string for any errors or inconsistencies
• Use validationQuery property to ensure each query has responses
• AutoReconnect property to reconnect if the connection is lost

Note that the problem of getting a “Connection timed out” error when trying to connect to a MySQL database is common and can have many causes, so it’s not possible to provide a single solution that works for everyone. The suggested solutions are general tips and may need to be adjusted based on specific circumstances.
