Actual behaviour

Fatal read error on socket transport
protocol: <asyncio.sslproto.SSLProtocol object at 0x1336afb38>
transport: <_SelectorSocketTransport fd=66 read=polling write=<idle, bufsize=0>>
Traceback (most recent call last):
  File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/asyncio/selector_events.py", line 801, in _read_ready__data_received
    data = self._sock.recv(self.max_size)
TimeoutError: [Errno 60] Operation timed out

However, this exception doesn't cause any problem per se in the execution of any code after this. The event loop runs fine and coro calling this also executes. The request also gets completed everytime.

Steps to reproduce

...
# Aiohttp persistent session
self._session = loop.run_until_complete(self.create_session())

async def create_session(self):
    return aiohttp.ClientSession()

...
# 'url' below is a third party server url
try:
      async with self._session.request(method,
                                       url,
                                       data = params,
                                       params = params,
                                       headers = self._headers,
                                       ssl = False,
                                       allow_redirects = True,
                                       timeout = aiohttp.ClientTimeout(total = 7)) as r:
   # Do something
except Exception as e:
      raise e

Is this still an issue? Can you provide a complete reproducer, including URL etc? Your reproducer appears to just be "make a request" with ssl disabled. Unless it's an ssl issue, millions of other users are making a request without this exception, so we'll need more to go on...
