Error 1901105 [Enrollment-EnrollmentSpecRequest(1901105)] appears during Knox Manage client enrollment

Last updated July 26th, 2023



Knox Manage (KM)


When enrolling your device through the Knox Manage client app, you may encounter the following error message:

Failed to enroll Samsung Knox Manage service. If the problem continues, contact your administrator. 1901105 [Enrollment-EnrollmentSpecRequest(1901105)]


The 1901105 enrollment error appears when a device’s status shows as Enrolled in your Knox Manage console. If you did not unenroll the device through a device command, the device status may not update properly.


In the left sidebar of your Knox Manage console, click Device, then locate your device in the list. If its status appears as Enrolled or Disconnected, select the device and click Unenroll > Force Unenroll.

After the unenrollment process is complete, you can then retry enrollment.
