How to solve ERROR download_api._download:228 HTTPSConnectionPool(host='optimise2.assets-servd.host', port=443): Read timed out. (read timeout=5)

The installed Anaconda startup error is as follows:

There is no problem starting now:

I have the same problem as @grosssven ; unable to update as detailed here: #11049 Looking at the log I see:

        "level": "ERROR",
        "line": 234,
        "message": "Invalid url https://www.anaconda.com/wp-content/uploads/2017/05/Webinar20-20Three20Ways20to20Move20your20Data20Science20Projects20to20Production.png",

       "time": "2019-07-02 21:53:59,565"
    }
]

This is the code inside ~/anaconda3/lib/python3.7/site-packages/anaconda_navigator/api/download_api.py line 233-235.

if status_code != 200:
        logger.error('Invalid url {0}'.format(url))
        return path

It does not have specific image in that page. I think better ignore this error. My error says:

2019-08-07 08:58:56,364 - ERROR download_api._download:234
Invalid url https://www.anaconda.com/wp-content/uploads/2017/05/Webinar20-20Three20Ways20to20Move20your20Data20Science20Projects20to20Production.png

same problem on every package I attempt to update; url paths vary slightly

Method 1. Pass the option to pip directly

pip --default-timeout=1200 install pyside2

Method 2. Set the default value

set PIP_DEFAULT_TIMEOUT=1200
