Do I need to allow my Nextcloud via CSP?

[JOduMonT]

Collabora is managed and hosted on a Cloudron

When Nextcloud is managed and hosted by Cloudron the connection works
but When Nextcloud is outside Cloudon the connection is not established.

Do I need to allow my Nextcloud via CSP?

To get this working, you have to login to the collabora app on your Cloudron (we have added a small config UI for that purpose) and then configure which origins can connect: https://docs.cloudron.io/apps/collabora/

Sorry to re-use this thread, but I tried adding two domains on a collabora instance and couldn't get it to work with both of them - it either gave me this 502 or some other WOPI error. Until I found this snippet and added it manually into the coolwsd.xml file.

The gui suggests you can add multiple domains via regex, split with pipes, but I tried all variations and just couldn't get it to work properly. Is there something that I've missed? One domain includes a dash, but with or without escaping, it just wouldn't work (only with the method above). Is there a trick to it to make collabora work with nextcloud domains?

The config settings UI in Cloudron just forwards the input value for https://sdk.collaboraonline.com/docs/installation/Configuration.html#multihost-configuration

thanks @nebulon, I thought as much, but what's the actual syntax? The same as in the suggestions in the UI? Should that also update the xml file? Does the app require a restart afterwards? I just couldn't get two hosts to work...

Yes it will put the raw value into the XML config and then also restart the collabora server in the background. For the actual value, I don't know either, you may have to ask the collabora community for that.
