[bug] Bot won't start. HTTP connection Pool error

[avexus]

I never used webpage to monitor bot activities, only console output is enough for me. So, I set up my conf as:
"websocket_server": false,
"websocket": {
"start_embedded_server": false,
"server_url": "127.0.0.1:4000"
}

But when I run to bot after git pull the mastery branch, I got
[requests.packages.urllib3.connectionpool] [INFO] Starting new HTTP connection (1): 127.0.0.1
,045 [socketIO-client] [WARNING] 127.0.0.1:4000/socket.io [engine.io waiting for connection] HTTPConnectionPool(host='127.0.0.1', port=4000): Max retries exceeded with url: /socket.io/?EIO=3&transport=polling&t=1473187694035-0 (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x0000000006B36E80>: Failed to establish a new connection: [Errno 10061] WSAECONNREFUSED',))

same as #5241

You can find a temp fix there, but this should be fixed
