[szj2ys]

Hi~
when i layer.login(), I received this error message:

gaierror Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/aiohttp/connector.py in _create_direct_connection(self, req, traces, timeout, client_error)
998 # across all connections.
--> 999 hosts = await asyncio.shield(host_resolved)
1000 except asyncio.CancelledError:

23 frames
gaierror: [Errno -2] Name or service not known

The above exception was the direct cause of the following exception:

ClientConnectorError Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/aiohttp/connector.py in _create_direct_connection(self, req, traces, timeout, client_error)
1009 # in case of proxy it is not ClientProxyConnectionError
1010 # it is problem of resolving proxy ip itself
-> 1011 raise ClientConnectorError(req.connection_key, exc) from exc
1012
1013 last_exc = None # type: Optional[Exception]

ClientConnectorError: Cannot connect to host app.layer.ai:443 ssl:default [Name or service not known]
