Why Does My Socket Connection Get Forcibly Closed by the Remote Host?

The existing connection of remote hosting: in -depth discussion "The existing connection is forced to close by the remote host" exception

This article discusses the fundamental reason why the "existing connection is forced to close" Socketexception in the client-server socket connection. This abnormal indicates that even if the session is in a state of activity and is exchanging data, a sudden disconnection will occur.

Potential reason:

Data transmission error:

The client may send damaged or invalid data to the server, which may trigger the server to terminate the connection.

• Network interrupt: Instant network problem (such as data packet loss or delay) may cause temporary disconnection connection, which causes Socketexception.
Third -party application error:
• Error in third -party applications may cause it to collapse or exhaust system resources, which causes the socket connection involuntarily. Close:
The remote host may deliberately close the connection for various reasons, such as detecting suspicious activities or forced execution connection restrictions.
• Failure exclusion skills:
• In order to effectively eliminate this problem, please consider the following steps:

Use Wireshark or similar network analyzers to capture and check network traffic. This will provide insights on data that is exchanged and identify potential transmission errors or format errors.

Check the log of a third -party application. If available, check if there are any abnormalities or errors in the log, these messages may clarify the problem.

Implement other log records in your code to capture the stack tracking of Socketexception and any surrounding events. This information can help rebuild event sequences that cause disconnected connections.

Log inference:
• The logs you provide show that when the socketexception occurs, it is trying to send the byte data packet. This indicates two possibilities:
• Connect to close the trigger:
The connection may have been closed, and then try to send data to cause abnormalities.

Code error: There may be errors in the code, resulting in sending air packets, which causes the remote host to terminate the connection.

Without other contexts and specific errors, it is difficult to give a clear answer. However, the problem may originate from errors in incorrect data transmission or client or server application.
