Hey,

This used to work fine but it's just been recently throwing this error:

An existing connection was forcibly closed by the remote host
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

We've getting it everywhere the code is being called even in the authorization window.

Has anyone else ran into this?

I fixed this by enabling SecurityProtocolType.Tls12 on app start.

This should probably be addressed in the utwit package, rather than everyone having to apply a manual fix themselves.

Thanks
