The log shows the WOPI URL is:

```auto
https://nextcloud.example.com/index.php/apps/richdocuments/wopi/...

```

but the editor is loaded from:

```auto
office.example.com

```

When `<wopi allow="false">` is enabled, Collabora Online Development Edition requires the storage host to match exactly. Since you are using **two domains (Nextcloud + CODE)**, you need an alias group.

Restart `coolwsd` after changing it.

About `/etc/hosts`

Using `/etc/hosts` inside the container is fine and should not break WOPI. Collabora only checks the **hostname string in the WOPI URL** , not DNS resolution. Since your logs already show `nextcloud.example.com`, name resolution is working.
