I have starting getting the error "VAMT reported that the response from the activation server did not match the request" when trying to do a proxy activate request. This is happening at multiple campuses with different servers and with different license keys for MS Office 2016.. I am running VAMT 3.1 on Servers 2008R2 and 2012R2 and getting the same results. The license keys show as active and validate on the MS Volume License Center and have been working normally previously.
Any help will be appreciated.
