Post Password Reset Login Loop

If you have changed your password, have you followed the steps in this article?

What to do after you change your Apple ID or password - Apple Support.  *

I learned today that if you have a VPN on with content filtering enabled it can block the connection between Apple and your device on a MacBook. If you have Admin rights on your computer you will have to create a new network profile in the settings menu under Network (you may have to also enable profiles as well) to connect to the open internet without the protocols for the VPN. Default profiles should be WIFi and perhaps ethernet. Anything that is branded is probably associated with your firm (if this is your work laptop or if you installed software on your personal laptop to use it for work) and necessary for their network protection but not for you to browse the open internet. If you are the Admin make a new network profile and drop the VPN components. If you are not the Admin call your tech support for your firm and let them know that you cannot login to icloud unless they temporarily remove the VPN software and let you login (at which point they can reinstall / reenable it). Hope this helps. I burned a lot of calories with Apple support to figure this one out.
