[Bug] Custom domain for status page is broken #3811

Describe the bug
The custom domain feature does not work anymore since 3.10
When accessing a configured domain it does not show the linked status page anymore. Instead we are redirected to login page as if it simply did not exist.

To Reproduce
Steps to reproduce the behavior:

1. Create a status page
2. Add custom domain name for status page (status.example.com)
3. Go to public url (status.example.com)
4. Get redirected to login page

Expected behavior
Status page should show up when accessing with custom domain name.

Desktop (please complete the following information):
