Hello @reza_fathi,
welcome to the community of Nextcloud

You started a topic in support category. Unfortunately you ignored the template and a lot of information to help you is missing. Please edit your original post and add all required details like Nextcloud version, webserver type and version, os version, related log file content. Use the support template.

Without additional information the community members cannot help you.

Regards,
wwe

Hello,

I’m having the same problem as @reza_fathi. When I try to open a document (managed by Collabora), on my main computer or my phone Android app, these 2 alerts shows.

1- Documents are not effectively contained: missing capabilities or namespaces

2- Slow Kit jail setup with copying, cannot bind-mount

these 2 alerts shows.

2- Slow Kit jail setup with copying, cannot bind-mount

since we have no idea how you’ve set up collabora, you can disable server audits to hide the messages. but that’s a workaround and not a solution!

workaround and not a solution!

-- logging.disable_server_audit=true # enable disable server audit

I am having the same issue.

I am using Caddy as a reverse proxy (if it matters).
This is a new install (today) of Nextcloud AIO. Using the built in Collabora container.

My Caddy block is (again, if it matters):

SubDomain.MyDomain.com {
        import logging nextcloud-aio
        reverse_proxy 10.3.0.249:11000 {
          header_up Host {http.reverse_proxy.upstream.hostport}
          header_up X-Forwarded-Host {host}
    }
        # Handle WebDAV redirects for CardDAV and CalDAV
        redir /.well-known/carddav /remote.php/dav 301
        redir /.well-known/caldav /remote.php/dav 301
        header {
        #Strict-Transport-Security max-age=15552000;
    }
}
