I can't log in to adobe creative cloud. everytime I try, the last page says "you are logged out" and sends me back to the first page.

Sorry, you are encountering problems logging into the Creative Cloud. It looks like you purchased a new membership.  Are you installing the applications on a computer that you personally manage? To use an individual Creative Cloud membership, the computer will need access to the servers and ports listed in https://helpx.adobe.com/enterprise/kb/network-endpoints.html.
