Hey there,  
Nice to meet you!

I have a Synology NAS with Nextcloud installed with Docker via a docker compose file. It is available through Swag (nginx reverse proxy).

I’m trying to setup a Collabora server, without success…

The problem is that after installing the docker image of collabora, **there is no way to have the ‘ok’ string showing**. I tried with the domain name, ip, localhost… My firewall is not a problem, I also tried without it. Curl gets me nothing. Curl --verbose get me:

> - TLSv1.3 (OUT), TLS handshake, Client hello (1):

A sample of my docker-compose file:

> collabora:  
> image: collabora/code:latest  
> container\_name: collabora  
> ports:  
> - 9980:9980  
> environment:  
> - aliasgroup1=https://\*domain  
> - extra\_params=–o:ssl.enable=false --o:ssl.termination=true  
> networks:  
> - nextcloud-network  
> restart: unless-stopped  
> cap\_add:  
> - MKNOD

I have already read many doc about it, but I’m knew at it and I didn’t find any answer.  
I tried with and without extra\_params.

I’m surely missing something, thank you in advance for your help!
