I would check the Oracle documentation for error "ORA-12705"
to get indications what can cause this error.
The message indicates that the problem is with the NLS files during "LOGON".
I suppose it is a server problem (but I am not sure). In this case,
you may find something relevant in the server log files.
Unfortunately, Oracle error messages are (following the Microsoft example)
often less specific than they should and could be:
ideally, they would tell which files or directory could not be accessed.
Maybe, the Oracle documentation helps you to fill the holes left
by the error messages.
