I successfully installed and configured SSL to my other 3 sites using the instructions of DigitalOcean https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04
But today, as I install a new SSL in my new site with LetsEncrypt I can’t get it to work perfectly. Although it is showing https when I visit the site but when I test it via ssllabs it shows “Certificate name mismatch” error.
*** One thing I noticed. When I visit my www sites with LetsEncrypt installed SSL and removed their www it redirects to one domain. Is this normal?
My webserver is nginx and I believe I correctly configured my server blocks.
Your help and suggestions are very much appreciated. Thanks.
