I’ve followed https://docs.nextcloud.com/server/18/admin_manual/installation/source_installation.html and https://docs.nextcloud.com/server/18/admin_manual/installation/example_ubuntu.html to perform a clean installation of NC18 onto Ubuntu 18.04.
According to https://nextcloud.com/blog/the-new-standard-in-on-premises-team-collaboration-nextcloud-hub/, “ONLYOFFICE’s community edition is installed by default on a new Nextcloud installation” but that didn’t seem to be the case.
The ONLYOFFICE connector got installed but the community document server did not. I have now installed that but any attempt to open an Office document within NextCloud produces a pop-up that says “ONLYOFFICE Cannot be reached. Please contact admin”.
There is an ONLYOFFICE settings pane and the Document Editing Service address is set to the same as the NextCloud server.
What did I do wrong? I cannot find much in the way of explicit instructions to get ONLYOFFICE working for NC18, which does suggest it should be very straightforward but something clearly isn’t working properly.
