How to resolve Navicat connection timeout

Question: Why does a connection timeout occur when using Navicat to connect to a database?

reason:

• Unstable network connection: The network connection is intermittent or has too high latency.
• Database Server Busy: The database server is performing intensive operations, resulting in slow response.
• Firewall or security software blocks connections: The firewall or security software blocks connections between Navicat and the database server.
• Improper configuration of the database server: Incorrect settings on the database server result in a connection timeout.
• Navicat is incorrectly set: Navicat's connection parameters are set incorrectly, resulting in the connection being unable to be established.

Solution steps:

1. Check network connection
Ensure the network connection is stable and there is no disconnection or delay.

2. Check the database server status
Connect to the database server through other client tools such as MySQL Workbench to check if the server is running and respond to requests.

3. Check the firewall and security software
Check the firewall or security software to make sure they allow Navicat to communicate with the database server.

4. Check the database server configuration
Login the database server and check the following settings:

• max_connections : Sets the maximum number of connections allowed.
• wait_timeout : The time to wait for a response before canceling the connection attempt.

5. Check Navicat settings
In Navicat, check the following connection parameter settings:

• Connection name: Make sure the connection name is correct.
• Host: Make sure the host address is correct.
• Port: Make sure the port number is correct.
• Database: Make sure the database name is correct.
• Username and Password: Make sure the username and password are correct.

6. Restart Navicat and Database Server
