Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_CONNECTION_ACTIVE with the numeric value 1230 and hexadecimal representation 0x4CE indicates that an attempt was made to perform an operation on a network connection that is currently active. This implies that the operation cannot be executed while the connection remains in an active state.
Error Details
The error ERROR_CONNECTION_ACTIVE suggests that there is a restriction or limitation imposed by the system when attempting certain operations during the active phase of a network connection. This could include actions such as closing, modifying, or terminating a connection that is currently established and being used for data transfer or communication.
Usage Context
This error typically arises in scenarios where an application or service attempts to manipulate a network connection while it is still in use. For example, attempting to close a socket or terminate a network session when there are ongoing data transfers could trigger this error.
Developer Interpretation
Developers should interpret ERROR_CONNECTION_ACTIVE as indicating that the operation they attempted on an active network connection was not valid at the time of execution. This does not necessarily imply a failure in the underlying system but rather a restriction based on the current state of the connection. Developers are advised to ensure that operations requiring exclusive access or modification of connections are performed only when the connection is idle.
