Messages are not sent when no network adapters are present (only loopback adapter)

This issue occurs on both Linux and Windows.

I have an Electron application that communicates with a backend running on the same machine via 127.0.0.1. The application uses SignalR for communication.

When the system has no active network adapters (only the loopback adapter), SignalR is able to receive messages from the backend, but it fails to send messages to the backend.

The issue is resolved when a virtual network adapter is installed and kept in the UP state, even if it is not actually used for network communication.

Version from Client app: "@microsoft/signalr": "^8.0.0"
