Unless you made a typo entering the error number the ORA-2004 should be a user application issued error.

Do you have any database logon event triggers?

$ oerr ora 21000
21000, 00000, "error number argument to raise_application_error of %s%s is out of range"
// *Cause:
// *Action: Use an error number in the range of -20000 to -20999, inclusive.
