Any Selenium experts out there?

I need some help with a selenium script I'm trying to run on a remote server. I'm using chromedriver to login to my Wordpress sites and I keep tripping a mod_security error ->

"Not Acceptable! an appropriate representation of the requested resource could not be found on this server"

I know the script works on my local machine using all the same packages, but when I deploy it to a server (Ubuntu and Nginx) it throws the error.

Any help would be appreciated!
