NTLM failed redirecting to login page

NTLM failed redirecting to login page

Hi,
 
When using the Robo Technician password reset template, upon clicking 'Add Request', I am getting a brief message saying NTLM failed redirecting to login page and then the request doesn't change the user's password or close the call.
 
This was once working fine.
