[Kea-users] HTTP_CONNECTION_HANDSHAKE_FAILED TLS handshake

[Francis Dupont]

The "wrong version number" error is returned by some crypto libraries
when TLS is expected but clear text HTTP is received.

PS: I say "some" because at least one has a dedicated code to detect
this very common error and emits a more user friendly error message
("http request" on recent OpenSSL versions, BTW old OpenSSL versions
have known security bugs so should not be used...).
