Would you mind sharing your virtual host (?or server block?) file?

What fixed it for me, was correcting a misconfiguration I had done in the .conf file that managed the nextcloud site. Specifically, I had it configured like this:

Alias /nextcloud "var/www/nextcloud" DocumentRoot /var/www

This, might have somehow messed up the forwarding of requests to the server. What fixed it though, was (obviously):

Alias /nextcloud "var/www/nextcloud" DocumentRoot /var/www/nextcloud

My nextcloud.conf (Apache) looks like this:

Alias /nextcloud "/var/www/nextcloud/"

<Directory /var/www/nextcloud/>
  Require all granted
  AllowOverride All
  Options FollowSymLinks MultiViews

 <IfModule mod_dav.c>
  Dav off
 </IfModule>

 Header always set Strict-Transport-Security "max-age=15552000; includeSubDomains"

 Satisfy Any
</Directory>

Looks like the reverse proxy and the rewrite rules are not in there. They are essential for communicating with the backend websocket server.

They are on the bottom of the README.md, but, here's a version similar to my setup:

ProxyPreserveHost On
        ProxyPass /whiteboard/ http://yourDomain:backendServerPort/ retry=0
        ProxyPassReverse /whiteboard/ http://yourDomain:backendServerPort/
                RewriteEngine on
                RewriteCond %{HTTP:Upgrade} websocket [NC]
                RewriteCond %{HTTP:Connection} upgrade [NC]
                RewriteRule ^/?whiteboard/(.*) "ws://yourDomain:backendServerPort/$1" [P,L]

The first lines setup the reverse proxy, while the rewrite rules...:

EDIT: Forgot to mention that the rewrite rules belong to the rewrite module of apache. This needs to be enabled, I don't believe its on by default on a debian/ubuntu system when installing apache. sudo a2enmod rewrite

Thanks for your reply. But I have to admit: after reading the README.md you mentioned, the scope of this app took me by surprise. I was expecting a simple app. However, there seems to be much more to it than that.

And therefore, I haven't RTFM. So, please don't bother explaining further details to me as I have to do my homework first.

So, thanks for your effort and for point out the obvious to me.

I guess, this bug ticket can be closed (PEBKAC).
