A "Connection Timeout" occurs when a device or application tries to connect to a server or network but does not receive a response within a specified time limit. This can happen for various reasons, such as network congestion, server overload, or issues with the device itself. When the timeout period expires, the connection attempt is aborted, and an error message is often displayed. Timeout settings can usually be adjusted in the configuration of applications or devices. For example, in web browsers or database connections, users can increase the timeout duration to allow more time for a response from the server, which may help in situations where the server is slow to respond.
