The usual way in which you obtain GPG public keys for email encryption or other purposes is via a key server. There are a few common ones out there, but it's also possible to run your own key server.

ssh into the system with:

ssh myusername@mydomain.com -p 2222

Select Add/Remove Apps then keyserver. You will then be asked for a domain name and if you are using FreeDNS also the code for the domain which can be found under Dynamic DNS on the FreeDNS site (the random string from "/quick cron example/" which appears after update.php? and before >>). For more details on obtaining a domain and making it accessible via dynamic DNS see the FAQ. Typically the domain name you use will be a subdomain, such as keys.mydomainname.net. It will need to be a domain which you have bought somewhere and own and not one of the FreeDNS subdomains, otherwise you won't be able to get a SSL/TLS certificate for it.

After the install has completed go to Security settings and select Create a new Let's Encrypt certificate and enter the domain name that you are using for the Key server. If the certificate is obtained successfully then you will see a congratulations message.
