Hello,

I have set up on my nexcloud collaborator office server.  
But it does not launch: “Could not establish connection to the Collabora Online server.”

I tried this:  
[Collabora integrated CODE server cannot start / not workin / not reachable [SOLVED] - ℹ Support / 📄 Collabora - Nextcloud community](https://help.nextcloud.com/t/collabora-integrated-code-server-cannot-start-not-workin-not-reachable-solved/90519)

But I got an error message :  
Logging at warning level to file: /tmp/coolwsd.vtYsohi6Xn/coolwsd.log  
Failed to listen on Server port(s) (9983-9983). Exiting.

Do you know where it can come from?

thanks in advance
