Collabora not working on nextcloud

[isZYKerman]

Hi everyone,
I run CODE and nextcloud on a TrueNAS 24.10 device, in which the Apps are migrated from k3s to docker-compose. I cannot obtain a public IPv4, so I'm all on IPv6. This results in that I can't simply follow the tutorial to bind the two services with my domain, for apps in TrueNAS do NOT support IPv6. Therefore I used docker network create office and connected both containers to it and in the nextcloud administration panel, I used http://ix-collabora-1-collabora-1:9980 as the server location, and it seemed to work ↓

But when I open any file an error will occur ↓

Do you have any solutions for this?

I see that

This is not the in-docker network domain and it is IPv6 only. Is that why the communication failed? If so, are there any solutions?
