Auth0 breaks when logging into two different auth0 protected sites from same session

I have setup Auth0 on both an OpenEdx website (at and a Jupyterhub website (at I can log into either OpenEdx or Jupyterhub. However, if I try to log into one and then the other, from the same browser, upon logging in, I get a 500 error. Is it possible the callback url is getting confused between the two of them? How would I fix this?

The goal is that they would be logged into both at the same time, so that they can get an iframe of one website (jupyterhub) from the other (openedx).
