Call to twitter rest api failing at around 10AM and 10PM



I am using .net Http client to call twitter rest apis. I have been seeing a failure pattern every day 10AM and 10PM. Every day around this time some of my calls to twitter fails with this exception.

'System.Net.Http.HttpRequestException: An error occurred while sending the request. —> System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.

Does twitter server periodically reset connections around 10AM and 10PM? Does it depends on some connection timeout?
