RemoteWebdriver - Could not start a new session

Question

I try to execute my testcase remotely. I used these commands on server to run Xvfb:

Xvfb :3 -screen 5 1024x768x8 &
export DISPLAY=:3.5

After that I tried to start Selenium standalone server, but this command failed:

java -jar selenium-server-standalone-3.5.2.jar -Dwebdriver.chrome.bin=/path/to/google-chrome -Dwebdriver.chrome.driver=/path/to/chromedriver

So I used this one:

java -jar selenium-server-standalone-3.5.2.jar

I get following log in terminal:

I initialized Webdriver variable as follows:

driver = new RemoteWebDriver(new URL("http://<my-server-ip>:444/wd/hub"),caps);

I executed project and got following error message:

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure. Build info: version: '3.5.2', revision: '10229a9'

How could I set, which browser should be started remotely? How could I start a new session?
