I can confirm that it works now, thank you.
I have other 2 issues now:
1. I don't know how to remove clusters.
2. I can create clusters if I mark them as "Converged Enterprise Edition" (M5/M7). However, if I mark them as Community Edition (M3) and click on the "Add new cluster" button, I get an "undefined" exception in a pop up.
Can you help, please?
Thank you again,
