"Dev key in use" license error

Dear Flexmonster Team,

We are getting a "Dev key in use" error in our development environment:

'Dev key in use': You are trying to use a development key on a real domain (<domain name>).

It seems the key is being flagged as a production key because our dev environment uses a .com domain but this environment is actually used for QA and internal purposes only.

Could you please help us whitelist this domain or let us know what configuration change is needed to allow the dev key to work there?

We use Flexmonster version 2.9.110.

Please let me know if you need any additional information to investigate this.

Thank you,
Veronika Andreeva
