Hi @Rhiz3K
Thank you for the detailed report.

In recent versions of CloudBeaver, the interface now requires a WebSocket connection to load table data. While WebSockets were used before, they weren’t essential - now, the table won’t load at all without a working WebSocket.

If the WebSocket connection fails (e.g., due to proxy, firewall, or server misconfiguration), the table will stay in an endless loading state.

To fix this, please check the following:

Ensure the server accepts WebSocket connections.
If you're using a proxy (e.g., Nginx), make sure it's configured to support WebSockets
Verify there are no firewall rules, SSL issues, or timeouts interfering with WebSocket traffic.
