Login Failure with gmail account in Auto Discovery.

Login Failure with gmail account in Auto Discovery.

I'm running v2.1.11 on Window XP pro, I get the same result if windows firewall is turned on or off. I can successfully log into my gmail account on my browser and have tried the following without any resolution:
1) Open Browser.
2) Navigate to gmail.com.
3) Sign in with your username & password.
4) Enter your password again as well as the CAPTCHA and sign in.
5) Re-launch PocketCloud and sign into Auto Discovery.
Do you have anything else I can try?
Are there any ports that need to be open on the company firewall?
