Failed to connect to MySql at Localhost:3306

Hello everyone,

I am trying to install a local installation and following the guide to install https://docs.appian.com/suite/help/17.1/Quick_Start_Installation_Guide_for_Windows_and_JBoss.html#-requirements

on the 9th step, when I am trying to setup workbench for  Appian, I get an error "failed to connect to mysql at localhost 3306 with user root" 

I am using the default instruction of root and password .

Any advice on where I am doing it wrong will be helpful.

Thanks,

Hemanth
