A few hours ago we started getting certificate expired errors on the endpoint https://tenant.au.auth0.com/userinfo.
This is currently broken login for our production app.
Could this problem be related to the changes to the CA for auth0 certs?

Update: we have updated our app node version (to update the list of CAs) and this has resolved the issue - there must have been a change in CA for the auth0 certs today
