CERT_HAS_EXPIRED error after login to our app

[inferlink]

Thank you @dan.woda. That was very helpful. I could figure out a way to fix it. How recent is the change made by the CA used by Auth0? And if you don’t mind, I do have more questions just so I understand the workflow better here. Does Auth0 receive all the certificates in the client’s trust store which in our case is node? And then Auth0 tries to verify the validity of all the root certificates it gets from node? Is that how this works? I am assuming all of this is separate from the SSL certificate we have for our web app site, is that correct?
