Hello McVitas,
Looks like you have a problem with creating a profile of user nx.
There are 2 possible reason:
1. Do you use domain users/LDAP/ActiveDirectory? Do you have non
standard restrictions for users?
2. It’s possible that default user profile on your host might be
corrupted. You can try to create few user accounts and check if
it’s possible to login on their desktops. If you experience any
problems, please refer to this Stack Overflow thread:
