hii @djshades2004 welcome to the collabora online forum

To ensure that no one else uses your Collabora Office server (hosted at `office.domain.online`), you can secure it by restricting access to only your Nextcloud server. Here’s how:

1. **Alias Group Security** :  
In your `docker run` command, you’ve already added the `aliasgroup1` to allow only requests from `https://nextcloud.domain.online`. This is a good first step.

2. **Edit Security Settings in XML** :  
To further restrict access, you’ll need to edit the `coolwsd.xml` configuration file. Since you’re using Docker:

3. **Forum Resources** :  
These threads provide detailed steps to secure your server:

4. **Explore More Solutions** :  
There are several other topics on the Collabora Online forums related to securing your setup. Explore the forums to discover more ways to restrict access and ensure a secure deployment.
