SIRIS, ALTO and NAS: Error: "You Have Exceeded The Number Of Unsuccessful Login Attempts Allowed"



When attempting to log in to the Datto device over your LAN or via the Partner Portal, you see a login screen with the error message, "You have exceeded the number of unsuccessful login attempts allowed. You can try again in five minutes."


  • Datto SIRIS
  • Datto ALTO
  • Datto NAS


The Datto appliance has locked the user's IP address out of the device UI due to more than five failed login password attempts within five minutes.

The Datto device will lock out the source IP address whenever there are five failed password attempts within five minutes. The IP block should only last five minutes and then allow five more attempts. If the device does not allow additional attempts after five minutes, or if you are unable to wait to re-attempt, contact Datto Technical Support for assistance.
