Hi @ilpvn, is this the only endpoint from Auth0 that is failing for you?
From your first message it seems you’ve already tried everything explained here: Auth0 is Down for all our Environments and all our Users are reporting an outage! - #12 by dan.woda
One other thing to check is which version of the SDK you’re using and upgrade to the latest one.
Can you try that and let me know how it goes?
