403. That's an error message. - After attempting to Login

Our account is not faulty as I am logged into Photoshop on my computer and my returning students have also had no problems.

I would guess, that the account is the problem, as returning students have no problems, but the newly created ones have. I would suggest, that you contact the Adobe customer care via the adminconsole. You seam to be an administrator of the Adobe Enterprise system. If you aren't, you will need the help of one of your administrators. Use the adminconsole to contact Adobe, as this will give you a more pointed support to the specificities of an Enterprise licence.

I also would recommend creating a fake student account, that you can use to test. When the issue has been solved, you can easily delete that one again.

Let me move this to the Enterprise & Teams forum for you, which I hope is the appropriate forum for your question.

I suspect that more than likely you will need to use the Admin panel (?) used to manage the accounts to contact technical support.
