I have recently upgraded one of our instances of UAG up to SP3 and all went well. However, upon connecting from a Win8 (Pro) tablet, using IE in desktop mode obviously, I get the following error:
Forefront UAG client components cannot run. The script signature public key file cannot be downloaded from the server. This might affect your site experience, depending on corporate access policy
I can "Ok" past this and log in ok but this results in endpoint components not running and no subsequent access into apps that require it.
I am also running a test instance of UAG SP3 and the same device can connect fine to this instance (endpoint components install and run fine). The test box is running an identical configuration - the only difference being its name and SSL cert.
Has anyone come across this error before and have any idea how to solve it? Much appreciated.
