Retirement: Resources interacting with Azure Automation using TLS 1.0/1.1 protocol will be blocked from March 1, 2025

Transport Layer Security (TLS) 1.0 and 1.1 are security protocols for establishing encryption channels over computer networks. Starting March 1, 2025, your resources interacting with Azure Automation using TLS 1.0/1.1 protocols won’t be able to connect to Azure Automation. All interactions through Webhooks, Agent-based/Extension-based User Hybrid Runbook Workers, Automation DSC navigating on the outdated TLS protocols will be blocked. All jobs running or scheduled on Hybrid Workers using TLS 1.0 and 1.1 protocols will fail.

Ensure your resources interact with Azure Automation using TLS 1.2 or higher. Follow these steps to disable TLS 1.0/1.1 protocols and enable TLS 1.2 or higher for Windows and Linux machines.
