I logged into auth0 and checked the certificate in the “Macine to Machine” to machine application (under advanced) but that certificate doesn’t expire until 2029.
I am also getting this error when trying to get the user data with the AuthenticationClient.getProfile with the auth0 node package - on the https://tenant.au.auth0.com/userinfo
@andrew24 I think there was a change in the CA issuing the auth0 certs today - we were running an older version of node - upgraded that and we are no longer getting the error (old versions of node have hardcoded CA list).
