Unable to connect to the IDE. Check if the IDE is running and CUBA Plugin is installed

Hi all,

Using CUBA Studio SE v.6.10.3 and IntelliJ IDEA 2018.3.5 when I click “IDE” in Project properties of CUBA Studio I get the error “Unable to connect to the IDE. Check if the IDE is running and CUBA Plugin is installed.”

From where I can download the CUBA Plugin?

I got the Cuba Studio and Premium Addons Subscription but I wish wait to start using the new Studio v.8.2 because I just started a project in CUBA Studio SE v.6.10.3 and my fear is the new product is not mature to end my actual project in a few days.

Thank you for any help !
Ivano C.
