Cannot submit domain name in AIO (only ipv6)

[Thomas_Geiger]

I use ipv6 to access my server, as my ISP uses DS Lite tunnel and opening my server via ipv4 is not an option for me.

I have tested running nextcloud as a snap package, which was automatically installed during the initial setup of the ubuntu server. I created an AAAA record and everything worked fine.

I then decided to deploy persistent instance using docker, nextcloud AIO and nginx reverse proxy.
However, when I try to submit domain in AIO interface, I get “DNS config is not set for this domain or the domain is not a valid domain! (It was found to be set to ‘’)”.

Is there any way to solve this problem?

It seems that it checks for an A record (ipv4):

Cannot submit DNS name

Yes, correct

I didn’t find the referring code (in the main server repository), so I don’t know if that could be easily adjusted for dual-stack and/or ipv6 only. You can check the availability from outside your host via ipv6, if that is working, you can consider this just as an invalid warning.
In such a case, you need to be careful to share links, since not everybody has ipv6. Even though, in some countries, ipv6 coverage reaches 70-80%, even on mobile networks.

Yes, it also checks for ipv6: all-in-one/php/src/Data/ConfigurationManager.php at e1b5ba884f68ef9bc14b1051bc72d97ff133637c · nextcloud/all-in-one · GitHub

However you might need to enable ipv6 in docker first: all-in-one/docker-ipv6-support.md at main · nextcloud/all-in-one · GitHub
