To reproduce

• 1step test.py:

from fastapi import FastAPI

app = FastAPI()

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

• 2step use uvicorn:

uvicorn test:app --reload --port 61111

• 3step open browser and open 127.0.0.1:61111,got no response,and check console got

NOTE:

• Please list tracebacks in full (don’t truncate them).
• If relevant, consider turning on DEBUG or TRACE logs for additional details (see the Logging section on https://www.uvicorn.org/settings/ specifically the log-level flag).
• Consider using <details> to make tracebacks/logs collapsible if they’re very large (see https://gist.github.com/ericclemmons/b146fe5da72ca1f706b2ef72a20ac39d). –>

Environment

Running uvicorn 0.14.0 with CPython 3.8.3 on Windows 10 x64

Additional context

Summary

• Problems occurs only when reload is enabled (--reload), not sure about --workers because we don’t use it

Solution

• Reset Winsock netsh winsock reset (From https://github.com/nonebot/nonebot2/issues/20#issuecomment-703582940)

Since I can’t reproduce the issue, and I didn’t receive any reply about it, I’ll assume that folks can solve the issue with the comment above: https://github.com/encode/uvicorn/issues/1145#issuecomment-1013610173.

I’ll be closing this, but if you have a solution that needs a PR, feel free to create it, and explain how to reproduce, and how the fix works. 🙏
