Hi there! Iâm trying to setup a VPS with Nextcloud and Collabora in docker-compose behind a nginx reverse proxy (jwilderâs + letâs encrypt companion, not modified). I spent the day at it (learning a lotâŚ).
At this point, in the Nextcloud interface, in the Collabora Online settings, I can connect to collabora via https and using the container name: https://nextcloud-collabora:9980. However, when I open a .ods or .odt document in my nextcloud files, I get no response for:
https://nextcloud-collabora:9980/loleaflet/46545ce/loleaflet.html?WOPISrc=https%3A%2F%2Fdrive.domain.tld%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F141183_ocksbm4b6wf3&title=documentName%20-%20Copy.ods&lang=en&closebutton=1&revisionhistory=1
With Brave Browser showing the sad face sheet of paper: nextcloud-collabora âs server IP address could not be found.
To fix this, I am trying to instead put my FQDN to my Collabora server in the URL textbox (https://office.domain.tld:9980). However, I then get: Could not establish connection to the Collabora Online server.
I am at a loss here, I donât know why my nextcloud instance wonât talk to my Collabora instance over the reverse proxy. Also, when I try to reach https://office.domain.tld, I get âOKâ displayed in the top left, which I think is normal. But when I try to reach https://office.domain.tld/loleaflet/dist/admin/admin.html, I get a prompt that never lets me log in. The docker-compose log says:
nextcloud-collabora | wsd-00008-00046 2021-01-09 07:12:31.739516 [ websrv_poll ] WRN client - server version mismatch, disabling browser cache.

nslookup office.domain.tls returns the external (WAN) IP from DNS Server 8.8.8.8
The VPS runs a Ubuntu 20.04 server with NExtcloud 20.0.2, Collabora Online app 3.7.11, Collabora server 6.4.3.1 (latest).

Here is nginx.conf, used by the web service. It has a 2nd server block for Collabora, which Iâm not sure is needed, taken from here: https://www.collaboraoffice.com/code/nginx-reverse-proxy/. I use a script to copy/paste the config, thatâs why there is a â\â before every â$â

And here is Nextcloudâs config.php:
<?php $CONFIG = array ( 'memcache.local' => '\\OC\\Memcache\\APCu', 'apps_paths' => array ( 0 => array ( 'path' => '/var/www/html/apps', 'url' => '/apps', 'writable' => false, ), 1 => array ( 'path' => '/var/www/html/custom_apps', 'url' => '/custom_apps', 'writable' => true, ), ), 'instanceid' => 'asdasdasdasd', 'passwordsalt' => 'asdasdasdasdasd', 'secret' => 'asdasdasdasdasd', 'trusted_domains' => array ( 0 => 'drive.domain.tld', ), 'datadirectory' => '/var/www/html/data', 'dbtype' => 'pgsql', 'version' => '20.0.2.2', 'overwrite.cli.url' => 'http://drive.domain.tld', 'dbname' => 'nextcloud', 'dbhost' => 'nextcloud-db', 'dbport' => '', 'dbtableprefix' => 'oc_', 'dbuser' => 'oc_admin', 'dbpassword' => 'asdasdasdasd', 'installed' => true, 'overwritehost' => 'drive.domain.tld', 'overwriteprotocol' => 'https', 'maintenance' => false, );
I have not added anything to my hosts file. I think that covers the information I have.
