in the other [post](https://help.nextcloud.com/t/help-docker-domaincheck-wont-accept-tailscale-validated-caddy-reverse-proxy/198429) and the [solution you referred](https://caddy.community/t/help-docker-caddy-suddenly-no-longer-can-find-dns-records/24983/20) caddy doesn’t have any config for Collabora - did you add this and is it reachable from Nextcloud (apache container) and client? I’m not sure it is expected with #tailscale but I can’t access your URL from outside.
