Check Session Registered Origin Error

I am trying to use checkSession and continuely receive

The specified redirect_uri https://mydomain.io/signin; does not have a registered origin.

I have verified that this url is in my allowed origins but continue to get it. The interesting thing is I see no origin passed in the headers of the check session call.

Hi @bigcountry,

Can you please DM me a HAR of the failed transaction?

I was able to get this working with support had to add the root domain to web origins and not just the signin and callback pages.
