So you've already got a certificate for alphafasionstyle.com, right? And you want to change it to pulamea.tk, correct?
This command says: "get me a certificate for alphafasionstyle.com and call the certificate pulamea.tk without including the hostname pulamea.tk in the certificate itself.
You have to add the hostname you require with the -d option.
That’s correct. When you run that command, you won’t have a certificate for the hostname alphafashionstyle.com any longer, because it will be overwritten by the new certificate for pulamea.tk.
