Something gone wrong

Hi,

I have a problem with the plugin. The error “Something gone wrong” had appeared on dashboard (sorry for the translation; I have an italian version – see image attached please):

This is the error log:

Last Error: 2017-02-23 14:50:44: exception 'Google_IOException' with message 'HTTP Error: (0) Could not resolve host: accounts.google.com' in /usr/www/users/[HIDDEN]/wp-content/plugins/google-analytics-dashboard-for-wp/tools/src/io/Google_CurlIO.php:123

Any suggestion?
