Hi, this is caused by #469 .

To solve the issue for now, you could either use Chrome (which works pretty well), or Selenium 3.4, or when using Selenium 3.5 and newer you must enable the protocol translating in Selenium (as mentioned in #469), using Selenium option -enablePassThrough false, like java -jar selenium-server-standalone-3.6.0.jar -enablePassThrough false.

Sorry for inconvenience :).

java -jar selenium-server-standalone-3.14.0.jar -enablePassThrough false

causes

In my case the only solution was:

Install chromedriver in a path that is in $PATH (/usr/bin or /bin)

and using in your test class:

$capabilities = DesiredCapabilities::chrome()

It works with executing Selenium standard way:

 java -jar selenium-server-standalone-3.14.0.jar

The passthrough option was removed in new releases. How can we solve it now?
