Confirming as above as well… used the stock sample from your github page and getting the same error:  
An unhandled exception occurred while processing the request.  
Exception: Correlation failed.  
Unknown location  
Exception: An error was encountered while handling the remote login.  
Microsoft.AspNetCore.Authentication.RemoteAuthenticationHandler.HandleRequestAsync()

Hi @bholman37

I’ve tested it now and I am not getting the correlation error. Can you please open a support case with us through an email to [developers@okta.com](mailto:developers@okta.com) in order to further investigate this issue?

Yes I will do that. FYI - I’m working on a Mac and when I test this in Safari 13.1 the stock sample from github works fine. When I test the exact same code on Chrome version 80.0.3987.149 (Official Build) (64-bit) I get the correlation error. I suppose I’m stating the obvious, but why would I build an application that uses an IDaaS that has browser version dependency issues? FYI I’m testing Auth0 at the same time and having the exact same problem… looks to be all about the SameSite breaking update coming out from Google. Do you guys have a fix for this? (will email this do [developers@okta.com](mailto:developers@okta.com) as well, but I’m thinking other folks will like to see okta’s response posted here)

FYI running localhost through https fixed this problem. Thanks to the Auth0 help desk for solving it for me.
