SSL certificate for IP based Nextcloud?

Question

Hello,
I am going to install Nextcloud on my old PC and because I will make it accessible through my home network's public IP I want to use SSL. However I do not want to buy a domain and the command `sudo nextcloud.enable-https lets-encrypt` requires a domain because Let's Encrypt requires a domain, and `sudo nextcloud.enable-https self-signed` brings up a warning in most browsers which makes my setup seem even more dangerous to my family members who will be using it as well. Is there any way to get something like Let's Encrypt on an IP?

Answer 1

self signed certificates always show you warnings. becoz Google or mozilla does not know what kind of certificate you have and they cant say it has "Verified" it. if you want a green tick you need to buy a valid domain and a verified SSL certificate.
and SSL won't work on IP address any more. let's encrypt or any other you need DOMAIN NAME

Answer 2

So you want to connect to your computer from outside the house like from everywhere on the planet with the public IP? It is possible to setup an IP Address with SSL but it's not really secure in most cases. You would need to install the ssl certificate on every device of your family members. And even the it would show a certificate error. So your family could never be truly sure that the connection is secure unless they are some 1337 Hackers.
