Good evening, I installed sellacious on two of my domains, one of testing and one working, but I can not activate the license (free) the error is "Could not connect to your website for activation. "
I had already installed it and the activation worked but I had to uninstall everything for a problem and now it does not work anymore. I also installed Joomla from the beginning.
What should I do ? what is the problem? Thank you

the sites are
https://store.exponoi.it and https://krim.exponoi.it
