what command did you use ?
what part of the code triggers this ?
there's not enough information as it stands

got the same problem.

i just run it on the local ENV with command uvicorn run:app --reload --host 0.0.0.0 ,
IT WORKS with no error.

The following operation will cause an error：

• Open the redoc/docs API documentation for the first time.
• Try to connect web socket that i expose.

Thanks for any help

it's hard to tell without seeing any part of your code that triggers this error, thanks for writing a minimal example that causes the exception
what uvicorn version are you using by the way ?

thanks for comment.
uvicorn version: 0.11.3

In the past two hours, i try to find reason that cause the error,what is depressing that i didn't.
And i restart network ,turn off proxy program, there's no error any more,it's realy confusing.
maybe the problem is the bad network and dns cache.
i'll submit detailed information in the next time,thanks again for the advice

i got the same problem:

main.py
`from fastapi import FastAPI

app = FastAPI()

@app.get('/')
async def root():
return {'message': 'hello world'}`

pip 19.0.3
pydantic 1.5.1
setuptools 40.8.0
starlette 0.13.4
uvicorn 0.11.5
websockets 8.1

Execute the following command in the command line：
uvicorn main:app --reload

and Open the following address in the browser
http://127.0.0.1:8000/

then i got the problem

I'm going to close this as stale @GeorgeMiao219 but feel free to reopen
that feels very similar to #727 which #729 fixed though.

我也出现了这个问题，刚开始很正常，突然重新运行就出现的，并且还无法定位到我们编写的代码错误，直接定位到了内部文件报错。经过调试输出发现raddr都是00000所导致的转换报错，尝试重新安装也没用，同样把最新的代码放到另一台电脑上可以使用（并且同一个局域网）
