I have the following problem
java -jar selenium-server-standalone-2.53.0.jar -role hub<
java -jar selenium-server-standalone-2.53.0.jar -role hub
Try replacing localhost with local IP
phantomjs --webdriver=8090 --webdriver-selenium-grid-hub=http://localhost:4444
with
phantomjs --webdriver=8090 --webdriver-selenium-grid-hub=http://127.0.0.1:4444
