[Docker test deployment: Trial has already been issued for this domain]

Hello everyone,

I am currently evaluating several solutions, also Blesta.

I deployed a test instance via docker on my localhost but the trial license isn't available.

Error: 

Sorry, a trial has already been issued for this domain and is no longer valid. To obtain a new trial key, please contact sales@blesta.com. If you'd like to purchase a license, please visit www.blesta.com.

Someone here who could help me out or am I missing something important?

Best regards
