Gmail IMAP connection failed

I have recently updated windows to the latest version (?1703) and it done several things to my laptop - it seems I cannot get EM Clinet to work now. I have seen several posts about this and it seems that the firewall may be an issue. I have allowed EM Client, tried with Firewall on and off and I am still getting the same error. 

Any help is much appreciated. 

Thanks
Dave
