Effective October 4, 2024, Transport Layer Security (TLS) 1.0 and 1.1 will no longer be supported by Bentley's Subscription Entitlement Services (SES).
Transport Layer Security (TLS) 1.0 and 1.1, which are security protocols for creating encryption channels over computer networks, have been in the process of being deprecated for several years due to security concerns with these older protocols. Microsoft has been phasing out the support for TLS 1.0 and 1.1 as indicated in previous announcements like the ones provided here:
Transport Layer Security 1.0 and 1.1 disablement
Azure support for TLS 1.0 and TLS 1.1 will end by 31 October 2024
Bentley Systems has also been phasing support out across our hosted services. Announcements like the one below describe the deprecation of support for Bentley Identity Management Systems (IMS) and requirement to update CONNECTION Client to avoid going issues forward.
IMS to deprecate TLS 1.0 and 1.1 as of July 18, 2020
With Microsoft's deprecation of TLS 1.0 and 1.1 in their Azure Cloud services, all of Bentley's cloud services, including SES and IMS, will not support traffic with these protocols after the first week of October 2024.
We recommend organizations update their Bentley client applications, such as CONNECTION Client, to the latest version that will support newer TLS versions.
For older Bentley client applications that have no update available but are still running on an internal machine, we recommend organizations administrators manually disable TLS 1.0 and 1.1 and ensure that TLS 1.2 or higher is available as the default secure protocol on the machine. The following article from Microsoft may help in that effort.
