 Hi,

 If I'm not mistaken, brackets are optional for an ipv6 address without
 port number. The problem is that it confuses django.

 {{{
 Invalid HTTP_HOST header: '2001:x:y:z:0:0:0:1'. The domain name provided
 is not valid according to RFC 1034/1035.
 }}}

 which can be fixed by changing `django.http.request.host_validation_re` to
 `_lazy_re_compile(r"[a-zA-z0-9.:]*")`

 but it also triggers an exception with `asgi.py`

 {{{
 2022/09/02 07:57:10 [alert] 422#422 [unit] Python failed to call
 'loop.call_soon'
 Traceback (most recent call last):
   File "/usr/lib/python3.10/asyncio/base_events.py", line 750, in
 call_soon
     self._check_closed()
 ValueError: invalid literal for int() with base 10: 'x:y:z:0:0:0:1'
 2022/09/02 07:57:25 [alert] 422#422 [unit] #23: Python failed to create
 'client' pair
 }}}
