Hello My domain is: nspca.co.za We requested our hosting provider to set up a Let's Encrypt SSL certificate for our client. The certificate was to be set up for the default domain nspca.co.za The domain www.nspca.co.za has a 301 redirect to nscpa.co.za When typing www.nspca.co.za into the URL on Chrome and Edge in a desktop and mobile version (after clearing cache as well) the following error displays: NET::ERR\_CERT\_COMMON\_NAME\_INVALID Our hosting provider has reported the following: "I have taken a look at the settings on your server and I can that the SSL certificate is assigned to "nspca.co.za" and that the bindings for this are set correctly. I have included a screen capture of this configuration below specific for the certificate for reference" ![nspca](https://global.discourse-cdn.com/letsencrypt/original/3X/8/c/8cc30a055ea95d54deef1003a8733659a08199ad.jpg) On reading the following thread in this forum: > [@There are issues with the site's certificate chain (net::ERR\_CERT\_COMMON\_NAME\_INVALID](https://community.letsencrypt.org/t/there-are-issues-with-the-sites-certificate-chain-net-err-cert-common-name-invalid/27986/3): > > T… in particular: ".......So, the solution was generate the certificate for the main domain (e.g: "[example.com](http://example.com)") but also for the alias or subdomain (e.g: "[www.appcoles.com](http://www.appcoles.com)")." we requested that hosting providers check the alias or sub domain to which there response was: "The certificate installed on the server does not include aliases or subdomains it is only for the domain "nspca.co.za"." Do we need to set up a 2nd certificate for the domain www.nspca.co.za? How do we resolve the error on the domain www.nspca.co.za? ---

if you browse to www.nspca.co.za no redirect happens if you use the HTTPS protocol the HTTP version redirect to HTTPS the certificate bound to that domain is also expired ![image](https://global.discourse-cdn.com/letsencrypt/original/3X/2/6/260d017de0453b5c733a8d2a84bc56d893769f2d.png) the certificate issued does not include the www subdomain.
