Hive MQ “Invalid handshake response getStatus: 426 Upgrade Required” connecting to AWS

HiveMQ Client Library
1

I am trying to connect to an AWS MQTT broker/server using the Hive MQ client library for Android Studio (v1.3.0) with an AWS pre-signed URL.

implementation("com.hivemq:hivemq-mqtt-client:1.3.0")
implementation(platform("com.hivemq:hivemq-mqtt-client-websocket:1.3.0"))

The parameters I am using are shown below with the sensitive information removed:

host: xxx.amazonaws.com
path: /mqtt?X-Amz-Algorithm=xxx&X-Amz-Credential=xxx&X-Amz-Date=xxx&X-Amz-SignedHeaders=host&X-Amz-Signature=xxx

This is my latest attempt to connect:

MqttClient.builder()
    .identifier(UUID.randomUUID().toString())
    .serverHost(host)
    .webSocketConfig()
        .serverPath(path)
     .applyWebSocketConfig()
     .sslWithDefaultConfig()
     .useMqttVersion3()
     .build()

But when connecting, I get the error:

com.hivemq.client.mqtt.exceptions.ConnectionFailedException: io.netty.handler.codec.http.websocketx.WebSocketHandshakeException: Invalid handshake response getStatus: 426 Upgrade Required
