Logs

Browser log

When i open the browser console's :

XHR GET https://cloud.iut-orsay.fr/ocs/v2.php/cloud/users/details?offset=0&limit=25&search=
[HTTP/1.1 404 Not Found 96ms]

[solracsf]

Without logs of any sort (Nextcloud, webserver) it is impossible to guess what could be wrong.

[Bevito]

I don't know If It can helps you, but in browser console's log, I get :

XHR GET https://cloud.iut-orsay.fr/ocs/v2.php/cloud/users/details?offset=0&limit=25&search=

Each time I try to access Users list.

In /var/log/apache2/access.log I get :
