It seems to be httpxs fault.
This works:
import httpx
r = httpx.get('http://192.168.179.35:8080/goform/Deviceinfo.xml')
print(r)this doesn't:
import httpx
import asyncio
async def main():
async with httpx.AsyncClient() as client:
r = await client.get('http://192.168.179.35:8080/goform/Deviceinfo.xml')
print(r)

This is solved with httpcore 0.13.6 (and was broken with httpcore 0.13.4).
