Return to Question

Please find below the code I am using:

Http http = new Http();
HttpRequest request = new HttpRequest(); 
String url='http://abc:8090/part/abc/abc/';
request.setEndpoint(url);
request.setMethod('GET');
HttpResponse response = http.send(request);
System.debug('Response:'+response);

I am able to access the url in the browser and I have added the base url in the Custom site settings too. But the above code does not call the web service. The reponse I get is

Response:System.HttpResponse[Status=Service Unavailable, StatusCode=503]

And when I change the url to 'https://th-apex-http-callout.herokuapp.com/animals' It works perfectly well.

Could anyone please help me if there is anything wrong with the url?
