Cannot communicate with groov Admin, groov View and Node-RED on GROOV-AR1; SYS LED continuously blinks green


Applies To:

Firmware for:

  • GROOV-AR1, GROOV-AR1-BASE, GROOV-AR1-SNAP

Versions Affected:

1.570.47 to 1.570.50

Resolved In Version:

1.570.51


Symptoms:

After you upload a new, valid SSL certificate to the groov Box using the groov Admin SSL configuration page, the groov Box becomes unreachable through groov Admin, groov View and Node-RED. This only happens when all of the following situations are true:

  • Ignition Edge is enabled
  • A valid CA-signed intermediate certificate is installed via the "Chained certificate" option in groov Admin.
  • The root CA certificate that signed the intermediate certificate is not one of the certificates recognized by the groov Box.

Workaround:

The only way to recover is to restore factory defaults. Then, try any of the following:

  • Disable Ignition Edge.
  • Switch to a self-signed certificate.
  • Switch to a CA-signed certificate with no intermediate or chain certificate.
  • Switch to an intermediate certificate that was signed by one of the root CA certificates recognized by the groov Box.

Resolution:

Opto 22 has resolved this issue.
