REST Assured - org.apache.http.NoHttpResponseException: <server_address>:80 failed to respond

Question

I'm facing this issue with REST Assured 3.0.3 intermittently, and the corresponding line of code is in a for loop.

It is a simple GET call like mentioned below:

response = given().setBaseUri(someBaseUri).setBasePath(someEndPoint).param("key", "value").header("X-Authorization-Token", my_auth_token).get();

I found a couple of StackOverflow answers suggesting to resolve the issue using ConnectionConfig, but I don't know how to resolve the issue while using REST Assured.

Below is the full trace:

Please help.

Answer 1

Adding this code seems to have resolved the issue. I haven't faced the issue even with the slower staging test servers.

Response response = given()...get();
ConnectionConfig connectionConfig = new ConnectionConfig();
connectionConfig.closeIdleConnectionsAfterEachResponse();

What I did not understand though is, how is the ConnectionConfig object working with Response object for this.
