I have a Nextcloud server running since some time now, everything working fine until two days ago.
As far as I can see, everything is working except the connection with the Nextcloud desktop app.
When I add a new account (I did that because I thought it could help me in my problem), the app send me to the login page, which is working, then the “Grant access” page, which does nothing. I can click on the “Grant access” button but it’s useless.
I’ve tried this process with Firefox, Chromium and Edge, nothing change. I’ve also tried on Debian and on Windows 10, same problem.
Nextcloud version : 17.0.1
OS : Debian Buster with some parts of Bullseye
Apache : 2.4.38
PHP : 7.3.11-1
I’ve check the access.log and error.log, nothing seems to be relevant to this problem.
Can someone help me?
