I am trying to make an asynchronous call to a wordpress site using HTTP callout method( using @Future). Everything works on sandbox and I was able to get 60% code coverage after hours of hit and trial methods. The issue started when it was deployed to production box, I am getting timeout error for every call to wordpress. I tried using request.timeout property with values ranging from 2 seconds to 120 seconds. Even then it gives me request time out error 408. My understanding with timeout is it will wait for specified time for a response before terminating with error. Also when it is an asychronous call, there should be no response. Please provide expert opinion on this topic. Below is my code
public class Wordpress_AsyncCall {
    
    @future (callout=true)
    public static void callwordpress(string endp){
        Httprequest req = new HttpRequest();
        req.setEndpoint(endp);
        req.setMethod('GET');
        req.setCompressed(true); // otherwise we hit a limit of 32000
      
        Http http = new Http();
        try{
        http.send(req);
        }
        catch(System.CalloutException e) {
           System.debug('Callout error: '+ e);
           }
        
   }

I am using an Apex trigger and asynchronous method to perform a callout to the JSON REST API for Wordpress. I continue to receive 500 Internal Server Error responses in my debug log when I edit a Salesforce record, but if I copy/paste the corresponding JSON into the Postman plug-in for Chrome the post is created as expected. Any help is appreciated, thanks!

I am trying to connect to carrier 411 webservice to pull some data but keep getting the below error everytime I call.  If i use the same soap request in SOAP UI tool its giving me soap response.  Could anyone please shed some light into it.

 

 

11:54:28.084 (84661000)|CALLOUT_REQUEST|[56]|System.HttpRequest[Endpoint=http://webservices.carrier411.com/wsLogin.cfc, Method=POST]
11:54:28.418 (418009000)|CALLOUT_RESPONSE|[56]|System.HttpResponse[Status=Moved Temporarily, StatusCode=302]

 

 

Below is the soap request

 

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <login xmlns="http://webservices.carrier411.com">
      <param1>user</param1>
      <param2>password</param2>
    </login>
  </soap:Body>
</soap:Envelope>

 

this is how i am calling the service,,,

 public static string getResponse(String request,String URL)
  {
    try{
      Http h = new Http();
      HttpRequest req = new HttpRequest();
       req.setHeader('Content-Type','text/xml;charset=utf-8');
      req.setMethod('POST');
      req.setEndpoint(URL);
      req.setBody(request);
      req.setTimeout(2000);
      System.Debug('HTTP Request is ' + req);
      HttpResponse res = h.send(req);
      
      System.Debug('HTTP Resonse is ' + res);
      return res.getBody();
    }
    catch(Exception ex) {
        throw ex;
        }
  }
 

This is the webservice  I am trying to call...I am not sure whether  i am missing anything in the header part....
