"Unable to verify authorization request state." while setting up SSO with OpenID

I'm working on setting up SSO through OpenID for our organization to embed Sisense into our own application, however after authenticating through our application's login page I'm not being redirected and instead I'm getting a 400 error with the message "Unable to verify authorization request state."

The error 400 and that message is being returned from https://[Our Sisense Site]/openid_callback

Does anyone know of a solution to this, or at least an idea of what may be causing it?
