Reset Password emails for not being sent to the customers

Problem statement

The reset password emails are failing with the error message “Failed Sending Notification”.

We can see the error in the logs:

"email_type": "reset_email",
"to": "[](",
"error": "The requestor's IP Address is not whitelisted"


As mentioned on Configure Custom External SMTP Email Provider you will have to configure your provider to allow inbound connections from Auth0. To see the list of required IP addresses, you can navigate to Auth0 Dashboard > Branding > Email Provider or from Auth0 IP Addresses for Allow Lists.
