2005 error reason:

After the local MySQL service is started, some functions of Navicat need to be connected to the Internet before they can be used. Since an error message says that the localhost of the host cannot be connected, localhost needs DNS resolution before it becomes the local loopback address 127.0. .0.1, when the network is disconnected, localhost is a string without parsing.

Solution:

1. Solve the network problem and successfully connect to the Internet.

2. When there is no network, open the connection properties and change the localhost of the host name or IP address to 127.0.0.1. That’s it.
