Possibly "User-agent" mismatch, which means the client's user-agent string did not match the expected value.

The client (e.g. browser or robot) sends its user-agent string in an HTTP header with every request to your server. For example, my browser sends "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5" -- indicating Firefox/3.5 on Windows XP, US English preferred.

It could mean something else, but since you didn't say where you saw this message, that's just a best guess.

probably correct - here's the setting

some CPV feeds only filter Geo, IP and UA mismatch

... meaning my traffic is filtered for these and no credit given unless it falls within allowed parameters.
