Does anyone know how to fix this issue?
I have installed manually the app cause it failed from the webui. I have copied from apps.nextcloud.com the downloadlink and done a wget to the destination. The I have extracted it and put to the apps folder. I have also applied the www-data permissions and then went back to webui and activated the app. Now when I want to open an office file or create a new one I get this issue from the screenshot
