Getting java.net.UnknownHostException while executing the basic automation script for Rest Api

I just executed the below script :

import io.restassured.RestAssured;
import static io.restassured.RestAssured.given;
public class Basics {
 public static void main(String[] args) 
 { 
  RestAssured.baseURI="https://maps.googleapis.com";
  given().
  param("location","-33.8670522,151.1957362").
  param("radius","500").
  param("types","food").
  param("key","AIzaSyDXR2YGnRu3-112ttezUsQ-T2zOkb6aafE").
  when().
  get("/maps/api/place/nearbysearch/json").then().assertThat().statusCode(200);  
 }
}

But I am getting an exception while running the script.

Exception in thread "main" java.net.UnknownHostException: maps.googleapis.com

Could someone help me to resolve this issue ?

Solution

You probably have a problem with your DNS. If you do nslookup maps.googleapis.com, you should see more or less the following:

Server:  questgedctvm.com
Address:  10.197.72.16 

Non-authoritative answer:
Name:    googleapis.l.google.com
Addresses:  2a00:1450:4002:805::200a
          216.58.205.74
          216.58.205.106
          216.58.205.138
          216.58.205.170
          216.58.205.202
          216.58.198.10
          216.58.198.42
          172.217.23.106
          216.58.205.42
Aliases:  maps.googleapis.com

If this is not what you're seeing (the actual IP addresses may differ, but you should get a bunch) then you have a DNS issue that you need to solve. It's not a Java issue.
