Many popular services are now enforcing TLS 1.2 for all access and integration services to provide the maximum cryptographic protection. There are known vulnerabilities in TLS 1.0 and TLS 1.1 that the latest version addresses while also improving security generally. If you are already on TLS but are not running TLS 1.2, then you should also plan to upgrade as quickly as possible. If you are still running SSL as your cryptographic protocol, you should plan to move to TLS as soon as possible.
TLS is the successor to the Secure Sockets Layer (SSL) cryptographic protocol and provides stronger security. The latest specification is TLS 1.2 as defined by the Internet Engineering Task Force (IETF) who control the protocol. Mark Graham, product manager for Azure DevOps Platform, provided no details beyond citing "unexpected issues," which pretty much covers the gamut of possibilities.Transport Layer Security ( TLS) is a cryptographic protocol that is used to secure communication over a network. If you're connecting over IPv6, TLS 1.2 is already enforced as a minimum requirement.

It did not affect users of the self-hosted Azure DevOps Server. This applied to all HTTPS connections to Azure DevOps Services, including web API and git connections to and. Azure DevOps services stopped accepting TLS 1.0/1.1 connections, and at a minimum required TLS 1.2, as of January 31, 2022.
