Hi Jana, It's a NTLM authentication prompt. Check if a valid NTLM SSO policy has been configured and applied. Navigate to Resource policies >> Web >> SSO >> General (SSO settings) >> check the settings configured on the non-prod device. If the NTLM SSO settings are not configured, create one and navigate to Resource policies >> Web >> SSO >> Kerberos/NTLM/Basic Auth >> Create a new policy for the user role (compare with non-prod box). Hope this helps! - Ray.
