[BUG] Cannot connect to remote selenium grid 4

[neswine]

What happened?

I am trying to connect the grid setup in my cloud. I am able to create the session but for some reason, I cant run the tests.
Seems like websocket connection is getting timed out.

I tried to setup in my mac M1 using docker and the tests run fine.

Command used to start Selenium Grid with Docker

SELENIUM_REMOTE_URL=<REMOTE_URL> npx playwright test

Relevant log output

Same here - @neswine have you been to find a solution?

[adamsjoe]

@neswine Also interested in any possible solution

[zhangjunqiang]

are you using docker-compose deploy selenium grid? the docker-compose return a path your pw cannot connect to

+1 With same problem.
Followed exactly as it is. https://playwright.dev/docs/next/selenium-grid#hub-and-nodes-mode
To Run HUB : docker run -d -p 4442-4444:4442-4444 --name selenium-hub-pw selenium/hub:latest
To Add GRID : docker run -d --name pw-chromium2 -p 5554:5554 --shm-size="2g" -e SE_EVENT_BUS_HOST=1XX.1X.X.X -e SE_EVENT_BUS_PUBLISH_PORT=4442 -e SE_EVENT_BUS_SUBSCRIBE_PORT=4443 -e SE_NODE_GRID_URL="http://1XX.1X.X.X:4444" selenium/node-chromium:latest
Then, i can see one node in the hub URL. Below is Test Code i'm executing:

import com.microsoft.playwright.*;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import java.nio.file.Paths;`

public class TestPWD {

    @DisplayName("Demo Test for Docker")
    @Test
    public void demoTest() {

        try (Playwright playwright = Playwright.create()) {
            Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(false));
            BrowserContext browserContext = browser.newContext();
            Page page = browserContext.pages().isEmpty() ? browserContext.newPage() : browserContext.pages().get(0);
            page.navigate("http://playwright.dev");
            page.screenshot(new Page.ScreenshotOptions()
                    .setPath(Paths.get("screenshot.png"))
                    .setFullPage(true));
            System.out.println(page.title());
            Thread.sleep(30000); //Just for sake of verifying the Live Session in GRID
            page.close();
            browser.close();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}

Executed with SELENIUM_REMOTE_URL=http://localhost:4444 environment variable like below

It Opens up like below:
