Comment (by dcf):

 It turns out this error message is not coming from meek-server itself. It
 is being printed by the net/http package, which does its own internal
 logging:
 https://github.com/golang/go/blob/go1.5.2/src/net/http/server.go#L1304
 {{{
                 if err := tlsConn.Handshake(); err != nil {
                         c.server.logf("http: TLS handshake error from %s:
 %v", c.rwc.RemoteAddr(), err)
                         return
                 }
 }}}

 We can disable this internal logging by overriding
 [https://golang.org/pkg/net/http/#Server Server.ErrorLog]. However these
 error messages are proving useful in debugging a current issue. An
 alternative is to replace ErrorLog with a Writer that greps for IP
 addresses and scrubs them.
