The simplest way to get rid of this error is to reboot/restart your IP Camera (IPC).
There are two reasons that will make gDMSS (DMSS Android version) show you this error message:
-you have entered a bad password: please check it / retype it
-someone has tried to access your account and it got locked
In both cases after you check that the username and the password are the right ones you should reboot your device!
If you have forgotten your password, you can use our DVR / NVR password recovery service.
If your camera’s account(s) have been locked, the simplest way is to either reboot it or to wait for at least 30 minutes before you retry. Also, be aware that someone – maybe a hacker – might try to login to your camera using an invalid password.
