Description

### Is there an existing issue for this?

- [x] I have searched the existing issues

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