External API invocation is failing with 502 error

[suneelkandali]

I wrote a Java function with below http client code snippet and deployed to my local Fn then function invocation failed with 502 error

I have Rancher Desktop on my local

HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("http://webcode.me"))
.GET() // GET is default
.build();

HttpResponse response = client.send(request,
HttpResponse.BodyHandlers.discarding());

System.out.println(response.statusCode());
Error message in log
