Nextcloud collabora docker loading document fails

@scubamuc

a full dual stack, thus having IPv4 and IPv6 addresses. usually the latter is priorised if both are available. this causes connectivity to fail.

@wwe could you confirm?

I can’t say for sure but definitely from my observation many or maybe all modern OS prefer IPv6 over IPv4.

@KarlF12

If IPv6 is not used in the setup, maybe the IPv6 stack could be disabled for the Docker network, or the entire host?

Docker by default doesn’t enable IPv6. It must be manually enabled if required

• Use IPv6 networking | Docker Docs
• all-in-one/docker-ipv6-support.md at main · nextcloud/all-in-one · GitHub

I can confirm CODE works with IPv6 connectivity if everything is setup right. especially router config differs from IPv4

• NC not reachable over Domain (IPv6) - #2 by wwe
• Probably DNS help with NC Docker + Collabora + Wireguard tunnel
