This doc assumes an local root CA certificate that issued
you server certificate.

But you have a self signed server certificate.

Setup and administration is usually easier with an small root CA
cert that issues your server certs.

(Especially if you have more than one server.)

It is possible your client refuses to import host certificates as
CA certificates...

(By the way: I assume you really wanted to use the certificate to
  authenticate the server.
  Setup of client certificates (used to authenticate the client
  against the server _requires_ a CA...) is also possible.)
