It has progressed far enough along the line that it has already processed the initial ClientHello from the client and is now trying to read some later record from the client. Because it has already processed the initial ClientHello we have already determined which protocol version is in use, so all records should use that protocol version in their headers. In the case of this error we've received something other than that version. This usually occurs because of some corruption of the data. Are you also using OpenSSL 1.0.2 on the client?
