I’m sorry to have to ask for support again. But I did not pass the 2 installation screen.
I have already changed server and DNS and it does not work. When I enter the data to create the user it does nothing and does not show me any error.
The first part passes OK because the license is valid, but apparently there is some call that does not let me continue. Could you please reset again the license and update your cache.
Or tell me for which file I can see the error.
I’m very sad 
Do the test yourself by creating any user and you will see what happens
