Why can Security Manager connect to a Cisco IOS router after configuration rollback?

A. This could occur because of one of the following reasons: –At rollback, the necessary configurations are copied from the TFTP server to startup-config, then the Cisco IOS router is reloaded. This reload causes a temporary loss in device connectivity. To resolve this, we recommend that you wait for the device to be reloaded completely, then try to connect to it again. –The configuration contains nonexisting or unauthorized username and password.
