- Wrong PIN code.
- The device is not registered. For SafeCom Controller refer to the SafeComController Administrator’s Manual and for SafeCom Go refer to the Howto chapter in the appropriate SafeCom Go Administrator’s Manual (Seelist in 1.11).
- Too many consecutive failed login attempts has caused Prevent login to be checked on the Identification tab in the User properties dialog(5.8.1).
If none of the above, it could be because the Windows system on the SafeCom server does not allow any more connections. If you also get a “Connection error. Login failed” when you try to log in to SafeCom Administrator, then you should restart the computer.
