Changes between Initial Version and Version 1 of Ticket #33976

-              initial
+              v1
 If I'm not mistaken, brackets are optional for an ipv6 address without port number. The problem is that it confuses django. In `asgi.py` we have
+```
+{{{
 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`
+```
+{{{
 /09/02 07:57:10 [alert] 422#422 [unit] Python failed to call 'loop.call_soon'
 Traceback (most recent call last):
 …
 ValueError: invalid literal for int() with base 10: 'x:y:z:0:0:0:1'
 /09/02 07:57:25 [alert] 422#422 [unit] #23: Python failed to create 'client' pair
+```
+}}}
