ERROR Google Analytics Connector 2:3 Error loading model settings

Hi everyone,

was anyone able to connect with his own google APIs(Google Sheet API)?

My KNIME workflow includes 3 nodes: 1. Google API Connector, 2. Google Analytics Connector, 3. Google Analytics Query.

here is configure for the 1st node:

above node executed successfully.

when I tried to config the configure of Google Analytics Connector, it shows me " Warning:Could not connect to the Google API", and Account, Webproperty, profile are all empty, meanwhile, error message shown in the KNIME console as:"ERROR Google Analytics Connector 2:3        Error loading model settings".

 What is the cause of this problem?
