Rename domain issue

Hello
During development I used the domain „kattgodis.hemsida.eu“. Now I have renamed the licensed domain to the correct „kattgodis.nu“ (Settings > System > Shopware account).

I have also renamed the domain at my Shopware account and uploaded a new hash file to the Public folder.

But it does not seems to work. Visiting kattgodis.nu gives a 500 error and the old, development URL still works. What have I missed?

Note: To get Shopware to to work on the server, the hosting provider created an symlink pointing to the Public folder. The main domain is „kattgodis.hemsida.eu“ for technical reasons and „kattgodis.nu“ is pointed (?) to the same place as a „addon domain“ in cPanel.

Regards, Magnus

UPDATE. I forgot to add the new URL under Sale channels > Domain. Newbee mistake.
