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.
What kind of Hostgator plan are you using? Do you administer your server with a cPanel control panel?
If so, you should be able to use the AutoSSL feature inside of cPanel, which will request and install a free certificate automatically. (According to previous discussions on the forum, that certificate might be from a different CA rather than Let’s Encrypt.)
A few hours after you point your domain to the HostGator server, you would receive a Comodo (cPanel branded) certificate issued by AutoSSL (on cPanel)
If you does not receive the certificate after one day, please contact HostGator support…
(cPanel branded certificates could take a long time before issued and installed, but HostGator choose that certificate instead of let’s encrypt certificate anyway)
