The get_client_ip function has a bug

```python
def get_client_ip(request):
peername = request.transport.get_extra_info("peername")
if peername is not None:
host, port = peername
return host

return "unknown"
```

The variable `peername` sometimes returns a value like this ('127.0.0.1', 19260), and sometimes it returns like this ('::1', 28891, 0, 0), throwing an exception: "too many values ​​to unpack". My comfyui desktop is now unable to start normally.
