UNsubscribe links don’t work in txt version

Version : 8.1.1

When mails bounce we receive a notification from the recipient mail service. In the txt part, the unsubscribe link that is written does not work anymore, clicking on it makes a blank page with “ko” written. All was working fine before 8.1.1.

We always use this link to unsubscribe bouncing subscribers, it is easier than manually doing with his mail address on the website.
