are you using your cloud-instance in SSL mode too?

Additional to be correct, you are using your own domain in the domainpart of your docker command?

Yep, i’m using my domain, i have have cert for this domain (internal domain).
And i run docker with domain in command.

ok then please post your nc-webhost config and collabora-webhostconfig.

If you are using a self signed cert you need to import the CA to your local instances and in the -nextcloud-installation-/resources/config/ca-bundle.crt

The next thing is, can your cloudserver and collabora, and your client connect to the internet?
if not, you need to download and replace some jquery snippets from cloudflare and googleapis and replace the links.
