Hosting Multiple HTTPS Domains from the Same Server with Let's Encrypt and Nginx
Ugh. Let's Encrypt will issue you a single certificate for multiple domains on the same server. It's easy to set up, too.It's not just for multiple subdomains like sub1.example.com and sub2.exmaple.com. You can have any unrelated domains you want on the cert.You don't need multiple IPs and you don't even need SNI with its legacy client compatibility problems (now mostly well past). Just get a certificate that covers all the domains you use.There's no reason at all to suffer with the setup and security and resource problems of SNI or multiple IPs outside extreme scenarios.
