@johannes, unchecking the "Prefer wildcard certificates" should be used only as the last resort if automatic external DNS detection does not work. Using external DNS and keeping the "Prefer wildcard certificates" ON should be ok for most of the servers. If auto-detection does not work please open a support ticket and let us investigate the server environment to find out why auto-detection had a false-positive. It would be much better in the long run to improve the auto-detection or fix the issues on your server if there are any.
