Description (last modified by Eric Burghard)

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'
