Hi ! Thanks for your answer. I cannot use it because I have deleted sub domains 5 times because my host provider had problem with sub domains. That’s the reason i used 5 times because I was recreating sub domain and then I was asked to delete it.
But the integrated plesk has a button that says “Lets Encrypt” and when pressing it, it creates a certificate that I cannot download from somewhere. It just embeds it into sub domain and I have no control. So now do I have to wait one week to enable another one (for my final subdomain that works now) and that’s it?
