Can you please include your server config as requested by the issue template:

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your Nextcloud installation folder

[leander091]

@nickvergessen I have already uploaded the server config, section "configuration" That is the same as the output of config:list

Do I need to provide more information?

[nickvergessen]

Right, I missed it inline, is spreed installed in /var/www/cloud.domain.com/apps or /usr/share/webapps/nextcloud/apps

[leander091]

All apps default installed by nextcloud are in the non writable folder. /var/www/cloud.domain.com/apps
The apps witch I have installed are located in the writable apps folder /usr/share/webapps/nextcloud/apps

[nickvergessen]

The problem is, that this dir is not accessible from the web, and the webroot you specified /apps2 is also invalid, so the error is expected.

If you move the spreed app to the non writable dir it should work without the log message.

[leander091]

I'm using a nginx alias to make the secondary app folder accessible from the web. Like this:

location ~ /apps2/(.*)$ { alias /usr/share/webapps/nextcloud/apps/$1; }

The browser is loading the assets (css ,js etcetera) without issues except from the warning message in the logs of nextcloud.

Do I need to include both app directories in the same webroot?

[nickvergessen]

Well the php code which is trying to make the path does not go through nginx ;)
So it fails to generate a path with the input, and then just continues with best effort, which works for you
