swoole-src: I get a SSL error swSSL_connection_error (ERRNO 1014)

Please answer these questions before submitting your issue. Thanks!

1. What did you do? If possible, provide a simple script for reproducing the error.

• I get many errors which is shown below.
• It is shown error when sending an image data (about 8KB) to SSL connected client.

NOTICE	swSSL_connection_error (ERRNO 1014): SSL connection#0[IP:Port] protocol error[127]

• I’m using Let’s encrypt certification file.

Short Script.

go(function () use ($packet, $channel, $synchronizer) {
...
    $data = 'data:image/jpeg;base64,' . base64_encode($packet);

    for ($i = 1, $chunks = str_split($data, $client->getChunkSize()), $loops = count($chunks); $i <= $loops; $i++) {
        $client
            ->enableBuffer(false)
            ->enableChunk(false)
            ->write(
                WebSocket::encodeMessage(
                    $client,
                    $chunks[$i - 1],
                    $i === 1
                        ? WebSocket::OPCODE_MESSAGE
                        : WebSocket::OPCODE_CONTINUATION,
                    $i === $loops
                )
            );
    }
}
...

• $packet is an image data.

• It is encoding text with WebSocket RFC.
