Describe the bug

I have deployed ownCloud Infinite Scale (oCIS) using Docker, and the service is exposed to the internet through Cloudflare Tunnel.

The server is running properly and can be accessed without issues via the web interface. Authentication works as expected on all clients.

However, I am experiencing a synchronization issue specifically with the ownCloud Desktop Client on macOS.

Expected behavior

1. The macOS desktop client should remain connected after login.
2. File synchronization should start normally, similar to the behavior on the iOS client.

Steps to reproduce the issue

1. Deploy ownCloud Infinite Scale using Docker.
2. Expose the service to the internet using Cloudflare Tunnel.
3. Install the ownCloud Desktop Client on macOS.
4. Open the desktop client and log in using valid credentials.
5. Login completes successfully without any error message.
6. Open the client Settings page.
7. Observe that the client status is shown as “Disconnected” and file synchronization does not start.
