Cannot connect anymore using the application

Nextcloud version : Version 2.5.1git
Operating system and version : 4.14.87-1-MANJARO x86_64
Apache or nginx version : apr 1.6.5-1 ; apr-util 1.6.1-3
PHP version : php 7.3.0-1

Hello, when I try to login through the nextcloud application, the window refreshes and brings me back to the login screen. When I try to connect via a web browser to http://ncloud.zaclys.com/, my login works fine. However, there is no file sync between my data folders and the zaclys servers when I use the web browser, I have to use the Nextcloud program for that.
I used to be able to connect via the application, but I believe the issue started to appear after I updated my whole system using “sudo pacman -Syyu”.

The output of the Nextcloud log :

The output my config.php file in /path/to/nextcloud : I could not find any such file, sorry. I used the “locate” and “whereis” command and it returned no such thing.

The output my system log using systemctl for “nextcloud”. Searching for “apache”, “nginx” or “apr” did not return any matches:

Any help welcome ! :slightly_smiling_face:
