Wordpress unable to recognise my Proofread Bot login / password

Hi There,
I have just made an account on proofreadbot.com which is working fine on website but my wordpress website is not accepting the login and password information. When I click on orange checkbox it give error message " Login failed to proofreadbot.com, please check your Proofread Bot username and password at the Plugin settings (click configure on the Plugins screen). "
Please advise accordingly. Thanking you in anticipation.
Thanks and regards,
