Nextcloud client for iphone ipad, Nextcloud Office, Files not opened correctly

audit du serveur: Documents are not effectively contained: missing capabilities or namespaces. Votre serveur est configuré avec des ressources matérielles insuffisantes, ce qui peut entraîner de faibles Slow Kit jail setup with copying, cannot bind-mount. Poorly performing proxying of all network requests. There was a time when it worked… does anyone have any idea?

It seems like the issue is due to server limitations and misconfigurations, causing Nextcloud Office and files not to open correctly on iPhone and iPad. Improving server resources and checking proxy and setup settings should help resolve it.

ok, Do you have any idea where I can find a tutorial to fix this proxy problem?
