## Common questions

### What Helm values and namespace are needed when installing Collabora CODE?

Use a Helm values file and install the chart into a dedicated namespace such as collabora. Without that file and namespace, the install may fail or you may mix Collabora with other apps on your cluster.

### What port should be reachable for Collabora CODE when using it from another computer?

Make port 9980 reachable from other devices. The editor uses a WebSocket connection, and without that access the browser may not be able to talk to the editor from another machine.

### Why might document editing fail in Nextcloud AIO behind nginx with 'socket connection closed unexpectedly'?

It can be caused by three interconnected issues: mastercontainer health, URL configuration, and WebSocket support.

### Does the LSIO Nextcloud image include Collabora Office?

The LSIO image does not support Collabora Office. It needs to be installed separately and run in a separate Docker container.

### Is setting up Collabora CODE with Nextcloud straightforward?

A Collabora forum thread reports that it can be difficult to get working with Nextcloud, and incomplete documentation makes setup confusing.
