Although there is generally nothing that Prosody operators need to do, servers using the new certificates may experience problems connecting to some other XMPP servers on the network.
Certificate Authorities (CAs) such as Let's Encrypt work by verifying that you own or control a domain, and then they issue you with a certificate that you can present to others as proof of this verification.
