Email Notification - Attached file link is not working

The link of a file attached in release/tag is not working from the email notification received from gitlab@mg.gitlab.com.

Link received in email is like http://group/subgroup/release/repo/uploads/xxxxxxxxxxxxxxx/xxxx1.zip which is not correct. Correct link is https://gitlab.com/group/subgroup/release/repo/uploads/xxxxxxxxxxxxxxx/xxxx1.zip.

https://gitlab.com is missing in the link.

Currently, I need to re-forward the release email notification to team members by correcting the link manually.
