It looks like you are changing lots of different settings all the time. Try and work on one issue at a time, and it will get better.
Looking at kourtney-kardashian.com first. It currently is and is giving a 526 error. This means that the origin does not have a certificate matching kourtney-kardashian.com, and you have set the SSL Mode to “Full (Strict)”. Set this to “Full” and that will resolve one error.
(You should try and get a real cert that matches your names on the Origin, then set the mode back to Full (Strict))
The other two seem to require SSL mode to be Full also, as connecting to the origin on port 80 returns a default error page.
