Controller Login Fails with "Remote end closed connection without response"

[ChromoX]

I have verified that I can login and have full use of the Unifi manager.

Whenever I try to initialize a Controller I would say I have a 1/6 chance of actually logging in. The other 5/6 times I simply have a trace-back that looks like the following:

Traceback (most recent call last):

urllib3.exceptions.ProtocolError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response',))

I've been attempting to remedy this issue in some form which included me adding a couple of lines for a Requests adapter for max_retries, but this doesn't seem to actually help.

It could be related to https://github.com/requests/requests/issues/2422 and https://github.com/requests/requests/issues/2448

The POST requests(Only _login) are the only ones that have the above issues. Once logged in get requests have no problem.

I have never been able to reproduce this issue. Have you gathered any additional information?

[ChromoX]

It might have been Docker networking stuff as the Unifi controller was in a container.

I switched over to using some module that uses ssh and goes direct to the AP instead of to the Unifi interface.

@ChromoX can you share with me how you solved your issues? I'm running in docker and am having some issues getting this to work aswell. Thanks,

I use this now instead of pyunifi: https://github.com/home-assistant/home-assistant/blob/master/homeassistant/components/device_tracker/unifi_direct.py
