Buggy source:
public void createRemoteDriver(DesiredCapabilities capabilities) throws MalformedURLException {
  if (!GridHandler.getInstance().containsSimilarBrowserKey(id)) {
    GridNode node=null;
    if (login != null) {
      System.setProperty(SshConnection.TEST_NODE_LOGIN_PROPERTY,login);

    }
    if (pem != null) {
      System.setProperty(SshConnection.TEST_NODE_PEM_PROPERTY,pem);
    }
    if (!hostAddress.equals(TEST_PUBLIC_IP_DEFAULT) && login != null && !login.isEmpty() && ((passwd != null && !passwd.isEmpty()) || (pem != null && !pem.isEmpty()))) {
      node=new GridNode(hostAddress,browserType,browserPerInstance,login,passwd,pem);
      GridHandler.getInstance().addNode(id,node);
    }

    options.addArguments("String_Node_Str" + GridHandler.getInstance().getFirstNode(id).getRemoteVideo(video));
    capabilities.setCapability(ChromeOptions.CAPABILITY,options);

Fixed version (ground truth):

  assertPublicIpNotNull();
  if (!GridHandler.getInstance().containsSimilarBrowserKey(id)) {
    GridNode node=null;
    if (login != null) {

    }
    if (passwd != null) {
      System.setProperty(SshConnection.TEST_NODE_PASSWD_PROPERTY,passwd);
    }
    if (pem != null) {
      System.setProperty(SshConnection.TEST_NODE_PEM_PROPERTY,pem);
    }
    if (!hostAddress.equals(publicIp) && login != null && !login.isEmpty() && ((passwd != null && !passwd.isEmpty()) || (pem != null && !pem.isEmpty()))) {
      node=new GridNode(hostAddress,browserType,browserPerInstance,login,passwd,pem);
      GridHandler.getInstance().addNode(id,node);
    }
 else {
      node=GridHandler.getInstance().getRandomNodeFromList(id,browserType,browserPerInstance);
    }
    GridHandler.getInstance().setHubAddress(publicIp);
    GridHandler.getInstance().startHub();
    GridHandler.getInstance().startNode(node);
    if (video != null && browserType == BrowserType.CHROME) {
      GridHandler.getInstance().copyRemoteVideo(node,video);
    }
  }
  if (video != null && browserType == BrowserType.CHROME) {
    ChromeOptions options=(ChromeOptions)capabilities.getCapability(ChromeOptions.CAPABILITY);
