Installed ServerWand on Linode for multiple sites, not-www is working but www is not found on the server

As my username suggests, I'm not the best with technical issues appearing, that's why I decided to install ServerWand as an easy way to have different sites with just one Linode, especially multiple WordPress sites.

After I bought my domain on Namecheap: mythicaltips.com, pointed to ns1-5.linode.com, installed ServerWand on a Linode, created records for www and mythicaltips.com, added the let's encrypt SSL I got the following problem when I go to www.mythicaltips.com

Not Found
The requested URL was not found on this server.

Apache/2.4.29 (Ubuntu) Server at www.mythicaltips.com Port 80

and also I can get:

Your connection is not private
NET::ERR_CERT_INVALID

If I go to mythicaltips.com the site works fine

What can I do to solve these issues considering I'm using ServerWand?
