What is error 1010 in rest integration?

[Viraj7]

var request = new sn_ws.RESTMessageV2();
request.setEndpoint('https://reqres.in/api/users?page=1');
request.setHttpMethod('GET');

request.setRequestHeader("Accept","application/json");

var response = request.execute();
gs.print(response.getBody());

This code is giving error 1010 , but If I change the endpoint to some service now end point its working fine .

Tried with the following code. Added 'User-Agent' to request header.

var request = new sn_ws.RESTMessageV2();
request.setEndpoint('https://reqres.in/api/users?page=1');
request.setHttpMethod('GET');

request.setRequestHeader("Accept","application/json");
request.setRequestHeader('User-Agent','telnet'); 

var response = request.execute();
gs.info(JSON.stringify( JSON.parse(response.getBody()), null, 4));

Result:
