Answer:
The error message "Internal exception java.io.IOException: An existing connection was forcibly closed by the remote host" usually indicates that a network connection was terminated unexpectedly while the program was running. This can be caused by a variety of issues, such as network connectivity problems, server-side issues, or problems with the program itself.
Here are some steps you can try to troubleshoot the issue:
Check your network connection and ensure that it is stable and working properly.
Check the status of the server you are trying to connect to and make sure it is online and functioning normally.
Check the program's log files for any additional information about the error.
If the problem is with the program itself, try restarting it and see if the issue persists.
If the problem persists, try running the program on a different machine to see if the issue is specific to the machine or network you are using.
If you are unable to resolve the issue, it may be helpful to contact the support team for the program or the server you are trying to connect to for further assistance.
