Your IT team must make sure you are running the latest version of Identity Agent. If you are not running the latest version, you may have problems logging in.
The information below is for IT teams.
Summary
To ensure sensitive authentication data is properly protected in line with National Cyber Security Centre (NCSC) and Internet Engineering Task Force (IETF) guidance and best practice, we stated that protective measures will be used to stop all use of TLS 1.0 and 1.1 from 1 July 2025.
Key date: TLS (1.0 and 1.1) will be retired and permanently blocked from use on Wednesday 15 October at 6:00am.
IT teams need to update to the latest version of Identity Agent. Failure to update could result in authentication issues and service disruption.
What this means for you
Users impacted by the retirement of TLS 1.0 and 1.1 will receive an error message and will be unable to authenticate. The error message looks like the image below.
The error message will read: "The underlying connection was closed: An unexpected error occurred on a send."
What you need to do
Anyone who sees the error message must immediately get in touch with their local IT team to upgrade their software.
If you are a supplier supporting the NHS or responsible for IT at an NHS organisation and you are requested to support, you should arrange for users to upgrade to the latest version of Identity Agent.
If local IT teams need further support, they should contact the National Service Desk.
