Hi,
We're seeing some errors today when our custom app integration is trying to authenticate. Our logs files are showing the following:
Trace: System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Authentication failed because the remote party has closed the transport stream.
Was working yesterday, and now failing. I couldn't see anything related to this in the August 29th change log. Has there been any other changes made overnight that aren't documented?

This is most likely because you aren't using TLS 1.2. Support for TLS 1.0 was recently disabled.
