[ LPR ] LPR2812 Unable to Login using VMS or ASManager? - 20260126

[support]

Question:
Why GV-LPR2812-DL shows Username and password error in VMS and Disconnected(Login Failed) message?

Answer:
If the GV-LPR2812 encounters related prompt messages when connecting to ASManager, VMS, and the web, it indicates that the username and password used for the connection are incorrect. If there are more than three failed login attempts, the device will automatically lock for 5 minutes and cannot be logged in.

ASM: Displays "Disconnected (Login Failed)" – the same message will appear if the controller's username or password is incorrect.
