[🐛 Bug]: I encountered a 504 error while using Selenium Grid with JavaScript.

[spartacus0816]

What happened?

I am developing an Automation System using Selenium Grid with JavaScript. I utilized Docker containers for the Selenium Grid.

There were 4 nodes.

I deployed a Node.js server on a remote Ubuntu server.

I tested it with postman.

But I could not get the response. The response will be HTML documentation.
Please help me.
Here is my code snipet.

Command used to start Selenium Grid with Docker (or Kubernetes)

sudo docker container restart selenium-chrome-1
sudo docker container restart selenium-chrome-2

Relevant log output

at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1495:16) {
errno: -110,
code: 'ETIMEDOUT',
syscall: 'connect',
address: '172.18.0.3',
port: 4444

Operating System

Linux

Docker Selenium version (image tag)

4.18.1

Thank for your consideration.

What is expected from this issue? Actually, what is the problem? Your NodeJS server returns that 504.

[spartacus0816]

I tested it in local machine. But it worked well.
But there was an issue when I connected remoteDriver.

What issue? It is complicated to help when not enough details are shared.

[spartacus0816]

Ok, no problem.
Here is my code:
driver = await new Builder() .forBrowser("chrome") .setChromeOptions(options) .withCapabilities(Capabilities.chrome()) .usingServer(remoteWebDriver) .build();
In above code, it worked well when I comment the .usingServer function.

I am using that code alone, and I am able to create a session using Selenium Grid. I am not sure what you plan to do with your app, but it seems to be out of the scope of what can be called an issue in Selenium.
