Run test_run failed with IPV6

[ischaojie]

When I run ./scripts/test tests/test_main.py, it test failed on IPV6 (return 502 status):

Actual   :502

please run uvicorn --version
please describe your network settings too, I dont see how the test suite could yield a 502
would need more info on what you're trying to achieve too

[euri10]

your hosts file seems ok,
can you run this

PyDev console: starting.
Python 3.9.9 (main, Mar  7 2022, 09:15:56) 
[GCC 10.2.1 20210110] on linux
from tests.test_main import _has_ipv6
_has_ipv6("::1")
True

I tried this before, and it return True:

In [1]: from tests.test_main import _has_ipv6

In [2]: _has_ipv6("::1")
Out[2]: True

Oh, that's because I use the proxy, It's fine now. Thanks again.

[euri10]

so pytest "tests/test_main.py::test_run[ipv6]" returns a 502, are you behind any sort of proxy, which even if it was the case would not make a lot of sense since we're hitting localhost here...
I'm kind of lost

[ischaojie]

I use clash to take over my proxy, test passed when I close it, Not sure the reason.🤯
