CFX Showing 'Invalid server (internal validation failed)' in KeyMaster

I have a Zap hosting server and it is set to use ‘Latest Version’ which is 6683 of the artifacts. But CFX license key keeps showing ‘Invalid server (internal validation failed).’ I generated an entirely new key and it allows the server to start up but then the Invalid Server message appears again and the RedM client will not list the server or find it when searching.

I can connect to the server fine but this error is preventing the server from showing up in the listing.

Is there some problem with detected the correct version of the artifacts on Zap servers?
