How to send files via https from ftp server?

Question

linux

Good afternoon!
I have access to ftp server with mp3. Login/password authentication.
There is also a server with clean ubuntu. Apache is deployed on the server with a screwed domain and an ssl certificate.
It is necessary to give users mp3 from this server via https.
Poke your nose, please, where to dig to set up such a bunch.

Expensive in terms of resources, crutch, but not cloning - there is no other way.
