Only local connections are allowed Chrome/Firefox Driver & Selenium

When I try to start a WebDriver with Selenium 3.14, 3.13 or 3.12 I get

"Only local connections are allowed.

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." error.

I can run tests with older Selenium versions without an error. I have already set the Envirioment Variables (e.g. webdriver.chrome.driver). Also I have tried "System.setProperty" method. I use jdk8, maven 3.5.4 on IntelliJ.
