Fitnesse in Linux server issue

I am having issue running Fitnesse on Amazon Linux 2 serve. Same configuration works in Windows 10 laptop. Here is the error I am getting when I try to run test in my Windows laptop against Fitnesse installed on Amazon Linux 2 server in AWS. Firefox browser and driver have also been installed but not GUI installed in Amazon Linux. I am not sure if GUI need to be installed in Amazon Linux.

Error:

__EXCEPTION__:org.openqa.selenium.WebDriverException: invalid argument: can't kill an exited process Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03' System info: host: 'ip-10-0-1-12.ec2.internal', ip: '10.0.1.12', os.name: 'Linux', os.arch: 'amd64', os.version: '5.10.109-104.500.amzn2.x86_64', java.version: '1.8.0_312' Driver info: driver.version: FirefoxDriver

Any help would be appreciated. Thank you.
