java.io.IOException: An existing connection was forcibly closed by the remote host.

I had this error when consuming my API from an outside PC, but when calling from the same PC it worked fine.

To fix to, I went to Control Panel
Right click in Java icon Go to Advanced Tab

Then check Enable Operating System's restricted environment Apply and Save

enter image description here

This fixed my problem.

Such behavior could be explained if the HTTP Client you use opens persistent connections to the server, and the server occasionally terminates them.

Normally, the connection to an HTTP server is closed after each response. With HTTP "keep-alive" you keep the underlying TCP connection open until certain criteria are met. What those conditions are depends on the server, which is free to close the connection after an arbitrary timeout or number of requests (just as long as it returns the response to the current request).

When the server closes such a connection the client usually reopens it again, and depending on implementation, may throw an exception or print a warning.

For example, Vert.x HttpClient (which opens persistent connections by default) also throws...

java.io.IOException: An existing connection was forcibly closed by the remote host

...when the server terminates them.
