Connection refused when trying to use rest over https

I'm having trouble trying to use https rest on my remote server. I have a remote server deployed using jelastic that is working in https. Im going to host another server in jelastic that would act as the client.But when I try to run this code:
String result;
Client client = ClientBuilder.newClient();
WebTarget target = client
.target("https://myresturi/Test");
Invocation invocation = target.request().buildGet();
Response response = invocation.invoke();
result = (String) response.readEntity(new GenericType<String>() {});
I get :
Caused by: javax.ws.rs.ProcessingException: RESTEASY004655: Unable to invoke request: org.apache.http.conn.HttpHostConnectException: Connect to mysecreturi:443 [mysecreturi/10.1.4.83] failed: Connection refused (Connection refused)

What is weird is that if I try to run this code localy in ecliple it works fine, and if I try using https://reqbin.com/ it works fine as well. If I try using http instead of https it works remotely as well

Pipeline call failed using Rest Template

I have a scenario where I want to pause a pineline using my spring-boot service. I am using Spring-boot and Go Pipeline API 16.1.0
Following is actual url available in GO API documentation to pause pipeline through CURL which is working perfectly
curl 'http://ci.example.com/go/api/pipelines/dev1-pineline/pause' -u
'username:password' -X POST -d 'pauseCause=testing Pause'
Above CURL URL working as expected but when I try to do same with RestTemplate it's not working.
RestTemplate function code is
public Object pausePipeline() {
String credentials = userName+":"+password;
byte[] encoding = Base64.encodeBase64(credentials.getBytes());
HttpHeaders headers = new HttpHeaders();
headers.set("Authorization", String.valueOf(encoding));
//headers.setContentType(MediaType.APPLICATION_JSON); // optional
String url = String.format("%s/%s%s", pipelineUrl,pipelineName,"/pause");
String data = "pauseCause=Monthend process started.";
HttpEntity<String> entity = new HttpEntity<>(data, headers);
return restTemplate.exchange(url, HttpMethod.POST, entity , Object.class).getBody();
}
Above code throws an exception when try to connect using Rest endpoint Exception stacktrace is
[o.a.c.c.C.[.[.[.[dispatcherServlet]] (http-nio-8080-exec-1) Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.client.HttpClientErrorException: 401 Full authentication is required to access this resource] with root cause

You might want to prepend Basic to your Authorization header. The relevant change in your code might be similar to the one below
HttpHeaders headers = new HttpHeaders();
headers.set("Authorization", "Basic " + String.valueOf(encoding));

Bing translator exception while integrating with java application

I am trying to integrate bing translator in my java application. I have registered to Microsoft azure cognitive service and Microsoft market place.
while executing below code
import com.memetix.mst.language.Language;
import com.memetix.mst.translate.Translate;
public class Main {
public static void main(String[] args) {
try{
Translate.setClientId(/* my Client Id */);
Translate.setClientSecret(/* my Client Secret */);
String translatedText = Translate.execute("Bonjour le monde", Language.FRENCH, Language.ENGLISH);
System.out.println(translatedText);
}
catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
}
}
}
I am getting below exception:

The datamarket url is where you get your client id and secret from. Is that where you're sending your translation request to? Should be something like
http://api.microsofttranslator.com/v2/Http.svc/Translate?
Also datamarket is being deprecated. You have to switch to Azure Cognitive Services
http://docs.microsofttranslator.com/text-translate.html

According to your referenced package com.memetix.mst.language.* in your code, I searched and found its source code on GitHub, repository on Maven, and an old repository on GoogleCode. I reviewed its source code, and discovered it wrappered the MS Translator Text API from Azure old datamarket web site. The library is out of date with the old REST API, the old website shows "THE MICROSOFT TRANSLATOR API IS NOW AVAILABLE ON THE AZURE PORTAL" and "IMPORTANT: An Azure account is required. Read the steps to get started on the portal here." So first you need to have an Azure subscription to create a Translator Text API service on Azure portal, then write code to call the new REST API. You can refer to my answer for the two other SO threads as below to know how to use the new REST API and call it via my sample code.
My answer for MS Translator returns empty response when used with Azure token shows the new REST API usage.
My answer for Microsoft Translator API Java, How to get client new ID with Azure which includes my sample code, it shows how to call the new REST API in Java.
Hope it helps.

Spring Neo4j - Cannot access unmanaged extension

I've deployed a Neo4j unmanaged extension. The unmanaged extension can be called using REST Client and successfully returned the result. The problem is when I try to call / invoke the unmanaged extension from another java class, it keep on throwing the 401 Unauthorized.
I used Spring RestTemplate to invoke the unmanaged extension.
My codes :
RestTemplate restTemplate = new RestTemplate();
PostPhotoRest postPhotoRest = restTemplate.getForObject("http://myneo4jusername:myneo4jpassword#localhost:7474/extension/servicetwo/postphoto/55b12d35-94fd-4297-bb18-e6040d7b7109", PostPhotoRest.class);

Jetty 9.3.3: ClosedChannelException when using HTTPS

request.method(HttpMethod.GET);
response = request.send();
httpClient.stop();
