Selenium version 4.6.0 is throwing HTTP504 error

I have installed selenium 4.6.0 in my local machine which works fine, within company VPN.

Then when I deployed it in our orgs kubernetes cluster (isolateComponents: true) I am getting HTTP 504 for my test cases.

No issues in the chrome node logs

But the router node I can see the below issue:

I have created the chrome node and router image with the following command for secure ssl connection to my website.

FROM selenium/node-chrome:107.0-chromedriver-107.0
USER root
ADD ssl.crt /usr/local/share/ca-certificates/ssl.crt
RUN update-ca-certificates
USER seluser

FROM FROM selenium/router:4.6.0
USER root
ADD ssl.crt /usr/local/share/ca-certificates/ssl.crt
RUN update-ca-certificates
USER seluser

Not able to understand the issue for the connection refusal, do I need to add proxy details? If so where can I add the same?

Solution

The networking was not the issue as I could curl the url from the chrome node easily without delay. The Issue was proxy , that i had to pass from my client code. I am using serenity and adding the below to the serenity property has no effect

serenity.proxy.http="abcd:1234"
serenity.proxy.sslProxy="abcd:1234"
serenity.proxy.noProxy="localhost,127.0.0.1,192.168.0.0/16,.....l"

Hence, I had to create a custom class like below

public class CustomCapabilityEnhancer implements BeforeAWebdriverScenario {


    @Override
    public MutableCapabilities apply(EnvironmentVariables environmentVariables, SupportedWebDriver driver, TestOutcome testOutcome, MutableCapabilities capabilities) {
        Proxy proxy = new Proxy();
        proxy.setHttpProxy("abcd:1234");
        proxy.setSslProxy("abcd:1234");
        proxy.setNoProxy("localhost,127.0.0.1,192.168.0.0/16,....");
        ChromeOptions options = new ChromeOptions();
        options.setProxy(proxy);
        options.setAcceptInsecureCerts(true);
        capabilities.setCapability(ChromeOptions.CAPABILITY,options);
        return capabilities;    }

    @Override
    public boolean isActivated(EnvironmentVariables environmentVariables) {
        return true;
    }
}

and in the serenity property I had to add the package name where the above code reside

serenity.extension.packages=com.mytest.org.application.features.ui.utils
