- When trying to connect to a Controller via FTP or Telnet the connection is failing even with known working usernames and passwords.
- Cannot ping controller after upgrade to 4.3.x

When connecting with FTP via an application such as Filezilla the error 'Bad username/password' is returned.
Via Telnet the error is simply 'Logon Incorrect' and the connection once again fails to complete
- FTP and Telnet have been intentionally disabled on the Controllers for Cyber Security purposes and will not be possible to use going forward.
- As mentioned in the Controller firmware release notes version 2.08.1018, Ping is disabled by default and can be re-enabled via Controller Commands:
- EnablePing = true
