I have a function which creates a WCF client (with certificate) and next is the call to https SOAP service. A function runs on a timer. Periodically (not constantly) the function falls in an error "WebException: The request was aborted: Could
not create SSL/TLS secure channel".
My problem is similar to described in this blog post https://social.msdn.microsoft.com/Forums/ru-RU/ca6372be-3169-4fb5-870f-bfbea605faf6/azure-webapp-webjob-exception-could-not-create-ssltls-secure-channel?forum=windowsazurewebsitespreview
After the restart the problem does not reproduced (some timer iteration) . But it appears after some time.
I tryed to add in code SecurityProtocolType.Tls12, change .NET framework version (4.5.2-4.6.1) for functions dependecys.. But the problem is still reproduce.
Because of the instability I got the impression that a function like run on different hosts. And this problem is reproduced only on a certain host.
The appearance of this error is very critical issue for me.
