kodi is not the cpanel name for your account, so if it is your intention to use the main account to login, you have the username wrong.
If you created a ftp account for a separate login, the username would be in the form
user@mydomain.pcriot.com, so again kodi would not be a valid user, which leave authentication to fail.
Verify your settings, including the domain used, you should use either yourdomain.pcriot.com or xo2.x10hosting.com as host.
