title: The decryption operation failed, see inner exception
body: <p>I am using Visual Studio 2017 and .NET Core 2.x. I have set up two projects. The first is the backend API (<a href="https://localhost:51637" rel="noreferrer">https://localhost:51637</a>). The second is the front end website (<a href="https://localhost:54146" rel="noreferrer">https://localhost:54146</a>). The front end website calls the back end API. They are both running locally on my machine.</p>
  
  <p>Problem is, when the front end tries to send a request to the API, I get this exeption</p>
