Notice

Here's the official report from Microsoft:

To ensure that Azure can provide the best level of security for our customers’ data, Azure Resource Manager will be deprecating support for incoming requests coming over TLS 1.1 and other older security protocols by Fall 2023. As such, to avoid any interruptions in your connections with Azure, we highly recommend that you migrate to TLS 1.2 and remove any dependencies on older protocols in your operating systems and work environments.

Azure Resource Manager already supports TLS 1.2; customers currently using this version will be unaffected by this move. However, we will require HTTPS connections coming from all customers to use TLS 1.2, and we will no longer provide backwards compatibility to older security protocols.
