Confluent Cluster Shutdown because of license problem

I installed confluent cluster on my development environment with 3 servers about 6-7 weeks ago. Last week I saw below error on my server.log
“io.confluent.license.ExpiredLicenseException: Trial license for Confluent Enterprise expired on”
Can’t I use confluent cluster for development purposes?

P.S. : I installed confluent cluster on 3 virtual centos 7.x servers

hey @slyyone

basically a trial license expires after 30 days.
from the docs:
"A trial (evaluation) license allows a free trial of commercial features in a production setting. " (Confluent Platform Licenses | Confluent Documentation)

for development purpose there is a developer license which can be used free of charge for an indefinite time.
The license is limited to a single broker setup.
