This casino restricted some countries. I noticed that when I was visiting the website to register. At first I was restricted and I got the restricted message. And I left the site to do another thing for about 1 hours plus and came back again to check it and register the casino and it worked.
This was the restriction message I received at first before working.

Was it that my country was in the restricted countries and later removed or it was not in the list but the message just pop up?
