You don't say, but from the reference to s3_pkt.c above I assume you are
using OpenSSL 1.0.2

This error means that the server has received a record that has the
wrong protocol version number in it. 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?
