Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:word.today

I ran this command:https://www.word.today/

It produced this output:Not Secure

My web server is (include version): nginx/1.10.1

The operating system my web server runs on is (include version):Ubuntu 14.04.5

My hosting provider, if applicable, is:Linode

I can login to a root shell on my machine (yes or no, or I don’t know):Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):no

Your certificate is for “word.today” and hence is not valid for “www.word.today” - the two need to match.
