Hey. lets encrypt silence should have a wildcard ??? Since I create a subdomain through the CNAME of the main domain, my ISP server control panel does not provide for a separate certificate generation for the subdomain. How to proceed?

  • Hello,

    If you have root access to your server you can issue and install the SSL Certificate manually using certbot. If you can let us know the specification of your server - OS, distribution, I can provide you with additional information.


Hello, @solomenmarketing

Could you please let me know what have you done so for and on which step you’re currently experiencing issues? You’ve mentioned that the CNAME is created but you can’t proceed with the SSL install. Could you please expand more on this, are you receiving any error messages and how exactly you’re trying to issue/install the SSL?
