Troubleshoot Licensing and `findface-ntls`

When troubleshooting licensing and findface-ntls (see Licensing), the first step is to retrieve the licensing information and findface-ntls status. You can do so by sending an API request to findface-ntls. Necessary actions are then to be undertaken, subject to the response content.

Tip

Please do not hesitate to contact our experts on troubleshooting by support@ntechlab.com.

Note

The online licensing is done via the NtechLab Global License Manager license.ntechlab.com. Check its availability. A stable internet connection and DNS are required.

To retrieve the FindFace licensing information and findface-ntls status, execute on the findface-ntls host console:

curl http://localhost:3185/license.json -s | jq

The response will be given in JSON. One of the most significant parameters is last_updated. It indicates in seconds how long ago the local license has been checked for the last time.

Interpret the last_updated value as follows:

[0, 5] — everything is alright.

(5, 30] — there may be some problems with connection, or with the local drive where the license file is stored.

(30; 120] — almost certainly something bad happened.

(120; ∞) — the licensing source response has been timed out. Take action.

"valid" -> "value": false: connection with the licensing source was never established.

curl http://localhost:3185/license.json -s | jq
