I guess you are running Apache proxy on the same machine as kobo? Your ip could be 127.0.0.1 then.
if setup is still showing dots, it means your setup in now ready yet even if you can login.
You can look at https://kf.yourdomain.tld/service_health/ and report what it says.
Once again, please read the whole thread Kobo-install http/https/certificate nightmare . You may find your solution within this thread.
