For the last month, I have gotten this message when I have been trying to use Express. It isn't blocked on our end. Is the site temporarily down, or is there a new web address? Thank you
This could be caused by too much device storage, meaning that you have downloaded too much files for your current computer size. The device does matter, if it is a computer it is your drive size most likely, whereas a Mac would be different.
Thanks for reaching out. Are you still experiencing this issue? If so, Have you tried using the other suggested browsers (Safari, Microsoft Edge, and Google Chrome) to see if it makes a difference? Also, try clearing the browser's cache and cookies and let us know if that helps.
