Navicat Connection Database: Differences and troubleshooting between remote and local connections

Remote connections and local connections access databases over the network differently. The remote connection accesses the database on the remote server over the Internet, while the local connection directly accesses the database stored on the local computer.

The difference between a Navicat remote connection and a local connection

Navicat Remote and local connections are the differences between how databases are accessed over different networks.

• Remote connection: Accessing a database located on a remote server via the Internet or a wide area network (WAN) requires network communication to access.
• Local connection: Direct access to the database stored on the local computer without communication over the network.

the difference:

feature	remote connection	Local connection
Access methods	Through the Internet	direct
speed	Affected by network bandwidth	Generally faster
Security	Network security needs to be considered	Usually safer
reliability	Affected by network stability	More reliable generally
Configuration	Requires network connection and firewall configuration	Usually no special configuration is required

Problem troubleshooting

Remote connection issues:

• Check if the network connection is normal.
• Make sure the database server and port are configured correctly.
• Check whether the firewall blocks access to the database.
• Try using different network protocols such as TCP/IP or SSH.

Local connection issues:

• Check that the database service is running.
• Make sure the database file is in the specified location.
• Check user permissions and make sure the user has access.
• Try reinstalling Navicat or database software.
