My Springboot application is deployed on a weblogic server which sits on my vps and when i run the method that intends to invoke an API method of another website i am returned with this error :

I have noticed that this only happens when i use Springs AsyncRestTemplate to invoke API calls.
ListenableFuture<ResponseEntity<String>> y = asyncRestTemplate.exchange(desiredUrl, HttpMethod.GET, new HttpEntity<>("result"), String.class);//.get().getBody();
boolean done = false;
while (done == false)
{
if (y.isDone() == true)
{
response = y.get().getBody();
return response;
}
}
} catch (InterruptedException | ExecutionException ex) {
Logger.getLogger(HTTP_Methods.class.getName()).log(Level.SEVERE, null, ex);
ex.printStackTrace();
}
The error
Connection reset by peer
is a response by the remote server (or firewall between them) stating that it will not proceed with completing this request.
It may well be a firewall denial, an SSL handshake failure, a proxy problem or even an HTTP failed request.
