WHD 12.7.8 email attachment links not working for Client Admin

Hello all, We recently upgraded from WHD 12.7.5 to 12.7.8 due to the recent security advisory.

When they do, they are presented with the following:

If they navigate to the ticket via the actual website as a client admin and click to download the attachment they can download it with no issue. I've already verified the link is valid and the Server DNS Name is set properly. Has anyone else out there in the community experience this yet?
