Cannot run parallel tests using selenium grid

I am running a simple demo test to test out parallel testing with appium, selenium grid and testNG. I am getting a session not known error.

Environment

Appium 6.1.0
selenium-server and selenium-java - 3.141.59
testng - 7.4.0

Details

My test is as follows:

`@Test
	public void test1() {
		DesiredCapabilities caps = new DesiredCapabilities();
		try {
			System.out.println("Execution started");
		 	caps.setCapability("platformName", "Android");
			caps.setCapability("deviceName", "R52N20ABC");
			caps.setCapability("platformVersion", "10.0");
			caps.setCapability("udid", "R52N20ABC");
			caps.setCapability("appPackage", "CP.Android");
			caps.setCapability("automationName", "uiautomator2");
			caps.setCapability("appActivity", "crc69e3927.ActivityLicenseBrowse");	
			caps.setCapability("noReset", true);
			caps.setCapability("systemPort", "8201");
			
	
			WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), caps);
			System.out.println("Execution ended");
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
			
	}`

The following error is seen:

This is my appium node log. Just wanted to mention, that I have 2 real android devices with exact same configurations - same Android versions, but one of them works fine with the testng script and the other one throws this error:

This log from hub shows the two devices both running the same test script. The R52N20ALVDN one fails with some BROWSER_TIMEOUT exception (to be noted that this tablet has been used for non-parallel testing before and works perfectly fine. No changes have been made to tablet), while ‘R52N20AM7XK’ works just fine eachtime:

Any reason why this fails on the one tablet?
