rest callout through salesforce to .net application

Hi, I am requesting a service to the endpoint using REST call.
Now this endpoint url is in client network. We are  passing  URLs in client network which works fine.
i have configured the endpoint under Remote Site settings and trying to send the request as POST AND GET  method to the endpoint via Apex class. I am getting  503 Service Unavailable response and the description of the body says 'Unable to determine IP address from host name'.
Since we this is just a HTTP URL , i tried creating a custom link and tried invoking the URL which works fine within the same app.
So I am not sure when I am able to access the endpoint URL via custom link within the app then why I am unable to access the same endpoint via Apex class?
Any suggestions would be highly appreciated.
Did you check the same with Postman?

<Http http=new Http();
     HttpRequest req=new HttpRequest();
        req.setHeader('content-type' ,'application/json');
        HttpResponse res= http.send(req);
               if (res.getStatusCode() != 200) {
               System.debug('The status code returned was not expected: ' +
                res.getStatusCode() + ' ' + res.getStatus());
