[hot-refresh] WebSocket connection to 'ws://localhost:50417/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

Describe the bug

During remote access, the browser reports the following error:

WebSocket connection to 'ws://localhost:50417/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

After investigating, we discovered that in aspnetcore-browser-refresh.js the host is hard-coded to localhost, so it never attempts to connect back to the remote machine.

const webSocketUrls = 'wss://localhost:50416,ws://localhost:50417'.split(',');
