Indeed Pull Now fails the server task is scheduled to run every two hours and also fails everytime so we can eliminate a busy server or network traffic reducing bandwidth causing the issue. I can perform this task from the EPo Hosting server via IE with the site going via proxy or with it bypassing proxy. Currently the EPo source site is configured and the proxy settings in EPo are disabled. Its almost as the Pull Now function does not run at all!?? I select the option to run pull now then go straight to server tasks and its already reported as failed!

I'd open a case with Support for this one. It appears there's a cryptography problem on the server - ePO is unable to decrypt information that it needs to run the task:
20130816155952 E #03376 NAISIGN Failed to aquire certificate private key provider. Error=0x80090016
20130816155952 E #03376 INETMGR Failed to decrypt using the certificate.
20130816155952 E #03376 INETMGR Unable to load asymmetric key
20130816155952 E #03376 INETMGR Failed to get decryption key for repository credentials
This will need to be looked at in more detail.
