Ahsay CBS download connect to the revocation server failed

Error when downloading Ahsay OBM main files from CBS.

Error:
Download failed: It was not possible to connect to the revocation server or a definitive response could not be obtained.

Resolution
This would appear to be a firewall issue with filtering or bandwidth throttling.

A Reseller has reported the following fix worked for them, however we have never had to implement this fix before.
Internet Explorer \ Security \ advanced un-tick ‘check for publisher’s revocation’ and ‘check for server certification revocation’
