unsubscription link not working

[tikovolpe]

Hello, how are you guys? I have a problem here getting the unsubscription link working. In the preview it works but when I trigger the email the link is not applied and so the subscriber is unable to unsubscribe. How can I solve?

The link arrived in the email, but when testing the cancellation, an error occurred.

Sorry! Something is wrong. Please try again

Can you help me?
