Hi Evgeni,

This is a known problem with our the IRIS 2018.2 Preview Community Edition listing which is under active development. We are in the process of correcting this, but it will take some time. When it is fixed you will have to redeploy the listing to pick up the changes. 

Since you have been directed to this listing, I assume, by an InterSystems contact the best way to get you up and running is to contact them (and me) directly through email so that we can get you set up with an evaluation key.  This is a conversation which should take place outside of this Developer Community post. My email address is Joe<dot>Carroll@InterSystems.com

Although Atelier will not work with this listing, yet, the non-atelier portions of the Quick Start experiences  as well as those hosted by InterSystems Online Learning will work. These can be found here.
