Zimbra version: zimbra-core_7.1.4_GA_2555.UBUNTU8_i386.deb

I received the xml license file today but the zimbra admin console gives an error message when I try to "Activate License" and "Manually Activate License"

respective errors:
Server error encountered:
message:system:failure java.net sockettimeoutexeception connect
timed out error code service Failure Method unknown
Details:soap:Receiver

Message root element must be ZimbraLicenseActivation error code
service LICENSE_ERROR method unknown details soap receiver

How can I activate the license before the old one expires?
