Having Issues Updating IDP Signatures

Hi Guys,

Currently having some issues updating IDP signatures on my devices, just realized this recently. Getting the error of:

error-message="Done;FetchingSignatureUpdate_tmp.xml.gzfailed, error:-1"] Failedtostartscheduledupdate(errorone;FetchingSignatureUpdate_tmp.xml.gzfailed, error:-1)

Has anyone had experiences troubleshooting this?

Do I need security policies to allow access to services.netscreen.com? 

Thanks
