Browserstack cannot forward the request Failed to connect to xxxxx (our corporate proxy server) java.net.ConnectException: Failed to connect

[semihural]

Hi,

We have zalenium running in our k8s cluster and enable Browserstack for Edge tests. We are using our corporate proxy server otherwise we did not able to connect between zalenium and browserstack or zalenium is not running properly in our cluster...So we able to connect but we received an error as below in somewhere after tests are started to run. It can be vary therefore I could not say it was happened for special moment or special test scenario.

I aware of that zalenium tries to connect http://hub-cloud of https.. I do not have any idea it can cause this but I can say there is no connection limit for our proxy server.

Here is how we set capabilities for edge.

caps.setCapability("browserName", "Edge");
                caps.setCapability("browserVersion", "latest-beta");
                browserstackOptions = new HashMap<String, Object>();
                browserstackOptions.put("os", "Windows");
                browserstackOptions.put("osVersion", "10");
                browserstackOptions.put("local", "false");
                browserstackOptions.put("debug", "true");
                System.setProperty("http.proxyHost","xxxxx");
                System.setProperty("http.proxyPort","xxx");
                caps.setCapability("bstack:options", browserstackOptions);
                webDriver = new RemoteWebDriver(new URL(nodeURL), caps);
                break;

Here is zalenium hub log
