How do I further debug the message "An authentication exception occurred"?

I have pretty much the same values for my development instance and my staging instance , but on the staging instance I get returned to the failure page with the message “An authentication exception occurred”, but I can’t find any php logs that have a auth related exception and I can’t see the error from the logs auth0 provides. Any suggestions how to further debug this?

Nevermind I figured it out the error is somehow my redirect_uri get parameter is losing an s so https it being transformed to http so it can’t find a valid redirect_uri in the application settings. Its weird no where in my code afait is the redirect_uri beings set to http.

Glad you were able to figure it out!
