First of all upgrade your docker installation to v27.0.1 or higher.
1. Then edit `/etc/docker/daemon.json` (or `~/.config/docker/daemon.json` in case of docker-rootless), add the below json:

```json
{
"default-network-opts": {"bridge":{"com.docker.network.enable_ipv6":"true"}}
}
```
> [!WARNING]
> This will enable ipv6 for all new docker networks by default!

Save the file.
```json
{
"default-network-opts": {"bridge":{"com.docker.network.enable_ipv6":"true"}}
}
```

And save the file.

2. Reload the Docker configuration file.

```console
sudo systemctl restart docker
```
```console
sudo systemctl restart docker
```

3. Make sure that ipv6 is enabled for the internal `nextcloud-aio` network by running `sudo docker network inspect nextcloud-aio | grep EnableIPv6`. On a new instance, this command should return that it did not find a network with this name. Then you can run `sudo docker network create nextcloud-aio` in order to create the network with ipv6-support. However if it finds the network and its value `EnableIPv6` is set to false, make sure to follow https://github.com/nextcloud/all-in-one/discussions/4989 in order to recreate the network and enable ipv6 for it.
