Fatal error: Uncaught exception 'Google_IO_Exception' with message 'Couldn't resolve host 'accounts.google.com''
This error appear because the server is failing to resolve the accounts.google.com
To correct this, change your resolvers to level3 or comodo, something that is independent from google. Example, put the following in /etc/resolve.conf file:
nameserver 188.8.131.52Once done, restart all the application that was using the google library. If you were using a web version of a php script, restart your apache. If you were using your own app, restart that app by either killing it manually or using your command line tools. This has to be done, is because Linux process will cache the resolver information from the start of it's creation to it's lifetime. Until it restarts, the old resolver information won't reset to the new.
