I’m running a Nextcloud instance (Hetzner StorageShare) and love using Nextcloud Talk. I’m using the same instance via 2 different domains. [nextcloud.domain1.de](http://nextcloud.domain1.de) and [nextcloud.domain2.de](http://nextcloud.domain2.de). I set up the high-performance-backend via the install script from sunweaver, and it works for the first domain 100%. The Install-script outputs a different shared secret for each domain, but in the talk-settings I can only enter one shared secret. This config results in talk only working when accessed via [nextcloud.domain1.de](http://nextcloud.domain1.de) and a signaling error when trying to access talk via [nextcloud.domain2.de](http://nextcloud.domain2.de) Is it possible to either add a second shared secret for the other domain, or give both hub-instances the same shared secret? Thanks in advance! 🙂 ---

Which of their service is the one solving “multi-tenant” setups? I requested their 14-days trial via the Nextcloud-settings page, but it only works for one subdomain as well. When accessing the settings page from one of the other domains, I get the “invalid backend” error message as well.. Thanks in advance 🙂 ---
