Hi I have installed Collabora Code for test on my shared hosting server (it’s a server I admin for all my hosting customers). Now that it works properly I’m thinking to offer commercial version of Collabora for my Nextcloud users. Does it imply I need to replace Collabora Code by the commercial version or it’s the same (I noticed deb repositories are not the same for both) ? If I need to replace I guess I need to backup the config file before replacement ? (I use the deb package on debian). Side question: I use a proxy reverse server to do the link between Collabora server and Nextcloud servers. If i understand well anyone on Internet can access that Collabora instance if he finds out the fqdn of it. Is there a way to restrict that in Collabora configuration ? or do I need to tweak the proxy reverse to accept only connections from 127.0.0.1 and public IPs of server ? Thanks Vincèn ---

Is there a way to restrict that in Collabora configuration this one I can easily answer - there is config “aliasgroup1”(…2|3) in docker and respective coolwsd.xml `alias_groups` setting where you can list systems allowed to access the COOL/CODE server - [CODE Docker image — SDK https://sdk.collaboraonline.com/ documentation](https://sdk.collaboraonline.com/docs/installation/CODE_Docker_image.html) > By default Collabora Online enables the first WOPI host that tries to connect. You can define the allowed WOPI hosts by passing environment variables. - [Fixing CODE Multihost Configuration](https://forum.collaboraonline.com/t/fixing-code-multihost-configuration/1001) - [21.11.3.4.1 - problem with multiple domains](https://forum.collaboraonline.com/t/21-11-3-4-1-problem-with-multiple-domains/991) ---
