Communication between backends

[lux-maker]

Hey there!

I am running a nextcloud that is accessible via multiple domains (e.g. nextcloud.domain1, nextcloud.domain2, nextcloud.domain3). I properly installed the HPB. All users can now use nextcloud Talk and talkwith /videocall each other as long as they are accessing my nextcloud instance via the same domain. However, I would also like to enable users to communicate with each other while they are accessing the nextcloud via different domains (e.g. one user accesses the nextcloud instance via nextcloud.domain1 and a second user accesses the nextcloud instance via nextcloud.domain2).

I think that this means that the backends in the server.conf file must be connected to each other somehow, but I can't figure out how.

Can you help me with that?

Currently, the [backend] section in my server.conf file looks like this:

[backend]
backends = backend-1, backend-2, backend-3
allowall = false
timeout = 10
connectionsperhost = 8

[backend-1]
url = https://nextcloud.domain1
secret = secret-removed

[backend-2]
url = https://nextcloud.domain2
secret = secret-removed

[backend-3]
url = https://nextcloud.domain3
secret = secret-removed

Thanks in advance!
