Hey guys,
because ipv4 adresses are nearly all used these days, my internet provider just gave me an ipv6 adresse. My problem now is that i just can’t get the server to host the cloud public because i can’t open any ports. Its a home server standing in my livingroom and in my lan everything works fine. What do i have to do to make the cloud go public? Thanks for the help! 
(Sorry for my bad english)
Your provider probably gave you some IPv6 prefix like /56 or something. You need to find that out. Next step is to assign IPv6 address to nextcloud instance. Then open firewall to allow incoming traffic to your nextcloud IPv6 address.
Just curious which provider (and country) is that?
First of all, you have to assign a static ipv6 to the computer who hosts Nextcloud, then the standard procedure is the same…
Can you visit amazon.com ?? Have only ipv6 is too early…
