Cannot post tweets using TLS 1.2 protocol (Twitterizer2.dll)

Question

We just recently disabled other protocols and enabled TLS 1.2 only. After doing so, the TwitterApp that posts tweets suddenly was not functioning properly. I suspect that the third party library was using SSL or lower versions of tls.

The Application was created using c# and is using Twitterizer2.dll.

Hi Have you try to set this in your POST REQUEST?

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
