or the name of the domain name is caused by parsing, you can use the following actions: Start-> run-> open:cmd-> OK, execute the command Ipconfig/flushdns after the VPN connection attempt.

3, due to the configuration of the exception caused by the inability to connect, although the user did not make any configuration changes,

However, due to internal failures in the system, the configuration (registry information) is abnormal, which is a common problem in Windows systems.

The processing method is to remove the configuration of the original VPN tunnel connection and re-establish a new VPN tunneling connection.
