Failed to Get the Application Certificates

This error messages in the Nymi Band Application.


The Nymi Band Application manages certificates to secure communications between the Nymi Band and the BLE adapter. When this error appears, Nymi Band Application cannot retrieve certificates.  Reasons can include:

  • The Enrollment Terminal cannot communicate with the NES server.
  • The L2 certificate on the NES server has expired.


  • Review the knowledge base for information about troubleshooting connectivity issues between the enrollment terminal and the NES server.
  • Replace the expired L2 certificates, the Nymi Connected Worker Platform—Administration Guide provides more information.

After you resolve the cause of the issue, log into the Nymi Band Application again. The certificate retrieve occurs automatically.
