java.net.SocketException: Connection reset

A java.net.SocketException: Connection reset is a runtime exception that is thrown when a connection is reset. This can be caused by a variety of issues, such as:

  • The remote host closed the connection.
  • The connection was reset by the remote host.
  • There was a network issue that caused the connection to be reset.

Here are a few things you can try to troubleshoot this issue:

  • Check if the remote host is up and running.
  • Check if there are any network issues that might be causing the connection to be reset.
  • Check the server logs to see if there is any information about the connection being reset.
  • Try increasing the value of the SO_TIMEOUT socket option, which specifies the timeout in milliseconds for blocking read operations. This can help to prevent SocketException errors caused by network latency issues.

If these steps do not help, it might be necessary to debug the code to find the root cause of the issue. You can try using a packet capture tool, such as Wireshark, to see what is happening on the network when the exception is thrown.

I hope this helps! Let me know if you have any questions.
