If the configuration check is unsuccessful the error report will provide diagnostic information for each of the mechanisms that it attempted to use to connect to the Identity Agent, this section provides guidance on how to interpret this information and what corrective action to take.
NHS Credential Management
Note that the first version of NHS Credential Management was called the NHS Identity Hub and the messages below relate to both versions.
NHS Identity Hub/Credential Management cannot be found
This may be because neither NHS Credential Management or the earlier NHS identity Hub have been installed on the device (which may be appropriate if an organisation has decided not to use it) or because the software is not running. Note NHS Credential Management does not automatically start after installation but will do so on a subsequent user login or machine restart. If NHS Credential Management will not start please refer to the troubleshooting section of the NHS Credential Management Installation Guide.
This message may also be seen if group policy has set the browser privacy and security settings to block third-party cookies. To enable use of NHS Credential Management the group policy needs to be updated either to allow all third-party cookies or to selectively allow them for [*.]localhost. For further details see the Configuration section of the NHS Credential Management Administrator's Guide, this can be found at NHS Digital Downloads - NHS Credential Management.
NHS Identity Hub/Credential Management (v...) is running on port 43485 but is not connected
This indicates that NHS Credential Management or the NHS Identity Hub is running correctly but an error has occurred whilst attempting to communicate with the Identity Agent. This is not an expected scenario. You should contact the National Service Desk for assistance if it persists.
NHS Identity Hub/Credential Management (v...) is running on port 55000 and is connected but cannot login to Care Identity Authentication
This indicates that NHS Credential Management or the NHS Identity Hub is running correctly but an error has occurred whilst attempting to check whether the Identity Agent has already logged in the user.
This may occur if the Identity Agent is not running, the user did not in fact log in to the Identity Agent before starting the test, the user logged out of the Identity Agent before completing the test, or the Identity Agent log in was unsuccessful. For guidance on dealing with authentication issues with the Identity Agent please see the Troubleshooting section in the Administration Guide included in the installation files.
If the above reasons have been eliminated, then you can get further assistance by calling the National Service Desk on 0300 3035035 or raising a call using the National Service Desk tool.
Windows Security Dialog
The Windows Security dialog shown below may be displayed if NHS Credential Management is run on a Windows 7 machine or on a Windows 8 or 10 machine that has had its Internet Options modified from the default values.

To rectify this issue the Local intranet settings in the machine's Internet Options need modifying as described in the Configuration section of the NHS Credential Management Administrator's Guide, this can be found at NHS Digital Downloads - NHS Credential Management.
