aaPanel_Kern I have tried several certificates, both free and paid, all give the same error. Also just now I SSHed into the server and checked under the path "/www/server/panel/vhost/cert/"my site .com" , there I could only see two files, "fullchain.pem" and "privkey.pem“，so I manually created "cert.pem" and pasted the SSL certificate in it, saved it. Although this still didn't work. But I read online there's supposed to be three files in this path, so mine the "cert.pem" was missing. Although even after I manually created and added this file, it still doesn't work, reports the same error when saving SSL info from aapanel.
