Why do I need to specify host and certs for TLS support?

[evilenzo]

I don't quite understand. I have a server that successfully runs shadowsocks. I wanted to add v2ray with TLS support and I really don't know which host, cert and key I should set there. What does it want from me? It runs on my server so why I must set some other host?

Buy a hostname somewhere, it will cost you some money. Issue a cert with acme.sh, its free of charge.
