I assume that you are trying to use different user accounts in a single server instance using your student license.
Unfortunately, it's not possible to sign in with multiple user accounts on the same server instance, whether it's a real or virtual server.
If you're using a single server as a group, please ensure that MATLAB is installed and that only one user is signed in at a time. If you want to sign in using your own account, make sure to sign out of MATLAB first before signing in with your account.
Hope this clarifies things for you!
