download to apple wallet

Hello! I have bought a ticket for a footballmatch and I have recieved a confirmation mail with a link to download to my apple wallet. But I am not able to do this. When I click the apple wallet ikon in the mail, it looks like the phone tries to redirect to a ticket-site, but then "jumps" back to the previous site I was on.

Can some help me solve this problem? Or have any experience with this?

All the best!
