I get this while creating API object

api = PyiCloudService('user', 'pass')

Here is the traceback

Connectivity exists!

Hi @Suncatcher !

Is it happening all the time ?

May you think with less fetch frequency it will fix this ?

Thanks.

I will try again and report back. I haven't used the script for a long time

I'm a little late to the part but for anyone who found this page via google search, see if the address resolves to an ip address successfully. In my case, my DNS was having problems which prevented me from accessing 'oauth.google.com' with near the same stack trace as seen here for 'p28-photosws.icloud.com'
