C#: Unable To Read Data From The Transport Connection : An Existing Connection Was Forcibly Closed By The Remote Host

This error occurs when an existing network connection is terminated unexpectedly by the remote host. There are a few possible reasons for this error:

  1. Server-side issue: The remote host (server) forcefully closes the connection, either due to a timeout, an error on the server, or the server going offline.

  2. Network issue: There might be network instability, such as sudden loss of connectivity, or an interruption in the connection between the client and server.

  3. Firewall or security settings: The remote host’s firewall or security settings may be blocking or terminating the connection.

To troubleshoot and resolve this issue, you can try the following:

  1. Check if the server is online and functioning correctly. Try accessing the server from a different client or device to see if the issue persists.

  2. Verify network connectivity and stability. Check for any network disruptions or try connecting from a different network to rule out network-related issues.

  3. Update or patch your application or library to the latest version. There might be bug fixes or improvements in the newer releases.

  4. Adjust firewall or security settings to allow the connection. Consult with your network administrator or hosting provider for assistance.

  5. Enable logging and diagnostics in your application to gather more information about the error. This can help identify any specific patterns or causes for the unwanted connection termination.

If the issue persists, it might be necessary to contact the remote host’s support team or your network administrator for further assistance in resolving the problem.
