问题 I enabled SSL in Visual Studio 2015 in order to implement Facebook and Google login locally. I changed the project URL in the Web tab of the project's properties to https://localhost:44300/ and decorated the controller with the RequireHttps attribute - ref @msdn. Everything worked fine locally. I reverted settings to HTTP to test something else and that caused me a problem when I tried to get back to HTTPS.
