[CentOS - Invalid Username found in configuration]

As the title goes I just can't get it to authenticate my username.

Editing /etc/pulseway/config.xml in so many ways I have no idea what is wrong.

<!--Account Information

  <Account Username="" Password="" UseCustomServer="false" CustomServerAddress="" />

Except for the fields username and password, I didn't change anything in the configuration file. 
 

I installed the agent on my Windows PC just to test it worked with no problems, now that I am trying to install the same thing on CentOS I get invalid username in configuration. Am I failing in formatting that the username should be written in the configuration file?
