my guess is that you would need to use asyncio.new_event_loop() instead of asyncio.get_event_loop().

But instead of guessing, giving a minimally reproducible example would be more beneficial.

I use Windows. I'm using the sample code from the readme:

import asyncio
from proxybroker import Broker

async def show(proxies):
    while True:
        proxy = await proxies.get()
        if proxy is None: break
        print('Found proxy: %s' % proxy)

proxies = asyncio.Queue()
broker = Broker(proxies)
tasks = asyncio.gather(
    broker.find(types=['HTTP',], limit=10),
    show(proxies))

loop = asyncio.get_event_loop()
loop.run_until_complete(tasks)

I get the following error:

PS D:\GitRepo\PythonTest> & d:/GitRepo/PythonTest/.venv/Scripts/python.exe d:/GitRepo/PythonTest/ProxyBroker2.py

I studied the link (aio-libs/aiodns#86), but it is not clear how to fix it! I ask for help in fixing the problem!

[surgutandrey]

Does this problem have a solution?

[ziloka]

yes
#147 (comment)

it is the only workaround for now

[surgutandrey]

What exactly should be done? In the provided answer, it is not clear exactly what actions are needed!

[ziloka]

Please look at this example

What python version are you running?

[surgutandrey]

3.12

[ziloka]

oh i forgot, my pull request haven't been merged yet. PR #147 will fix this.

[surgutandrey]

what specific action should be done? Nothing is clear in this discussion

[ziloka]

add the following code after you import asyncio

if sys.platform == 'win32':
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
