Unsubscribe link returns "Fatal error. Access Denied. Client address is not authorized"
Answer ID 9740   |   Last Review Date 07/22/2019

Why can't our customers unsubscribe from our mailings?

Environment:

Mailings, Configuration Settings
Oracle Service Cloud

Issue:

Unsubscribe button is not working in mailings from mobile network.

Resolution:

This message is returned when the “SEC_VALID_ENDUSER_HOSTS” configuration setting has been enabled.

Since the "Unsubscribe" link will redirect end-users to the Customer Portal page, it is expected behavior to receive "Fatal error. Access Denied. Client address is not authorized" as long as the IP address of the end-user isn't listed in the configuration setting mentioned above.

If you decided to enable “SEC_VALID_ENDUSER_HOSTS”, an alternative would be to remove the "Unsubscribe" link from your mailings and have the end-users reply back if they wish to unsubscribe. The removal of global opt-in would need to be done manually.
