Hi Teresa and welcome to E-Learning Heroes :)

Thanks for reaching out and letting us know what you are experiencing. Ask your network admin to open port 443 and add the domains in this article to your organization's allowlist for your Articulate 360 apps to work properly.

It looks like your original issue with signing in was related to your firewall as well, so that should not be related to your ability to sign in and we've added lots of features and fixes since the update you are on.

Let me know if you have any questions. I'm happy to help!
