Error while downloading APK: HTTPSConnectionPool

[avikmrr]

Hi All,

I am facing an error while downloading an apk:

HTTPSConnectionPool(host='android.clients.google.com', port=443): Max retries exceeded with url: /fdfe/details?doc=com.facebook.lite (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x108174950>: Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known',))

Does anyone has got this error before or know how to fix it? Your response is highly appreciated.
