SSL from scratch

On an Ubuntu 18 VPS I used this

to successfully install and run Icecast on https. I used a sub domain, and all went well.

I then installed LT using git clone. LT could not be found at

Any pointers as to where I went wrong or where the LT install/login page can be found ?

Also, on this fresh install, Opus is not working. How do I get it to work ?
