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

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…

This fixed my problem.
