Wrong SSL cert returned on gitlab pages with multiple domains

Summary

I added a second custom domain to my pages website (gitlab.io). After this the first custom domain I added (with custom ssl cert) is returning the gitlab cert instead of the custom domain cert. Before adding the second domain (without cert) it worked just fine.

Domains, see screenshot.

Steps to reproduce

Not confirmed;

  • adding a second custom domain (without ssl cert) to a pages site, when there already was one with a custom cert.

Expected behavior

Pages return SSL cert for the requested domain.

Actual behavior

Servers return SSL cert for *.gitlab.io
