Check for errors in Azure Notification Hub.

When I made a request from our system to send a push notification via Azure, the following error was returned.
"Received fatal alert: protocol_version"
I would appreciate it if you could tell me the cause or how to investigate the cause.

Thank you.

    Thanks for asking question! Could you please confirm which TLS versions you are using?

    As to ensure a higher level of security, Notification Hubs as disabled support for TLS versions 1.0 and 1.1 on December 31, 2020 (extended from April 30, 2020). And its recommended that you review your all of your applications that use Azure Notification Hubs, to ensure that they use the most applicable libraries and TLS stacks that support TLS 1.2.

    Please let us know if issue remains.
