# License Has Expired

The collector’s log indicates `license key is invalid` and `token is expired`.

### SYMPTOM

The collector’s log indicates that the license is expired. For example:

```log
Jun 14 13:49 23 ld6r3-elastiflow flowcoll[1763]: 2023-06-14T13:49:23.219+0100	fatal	flowcoll/flowcoll.go:74	exiting flowcoll because your license key is invalid	{"code:", "license/invalid", "reason", "token is expired by 3071267s"
```

### PROBLEM

The ElastiFlow license has expired.

### SOLUTION

Three ElastiFlow license tiers require a valid license key: Basic, Standard, and Premium.

* If your Basic License has expired, you may [request a new license key, valid for one year, from the ElastiFlow website](https://www.elastiflow.com/basic-license), update the key in the collector's configuration, and restart the collector.
* If any other license, Standard or Premium (including Trials), has expired, please contact <sales@elastiflow.com>.

You can learn more about ElastiFlow licenses and subscriptions [on the our website](https://www.elastiflow.com/subscriptions).
