After read source code I found The org.springframework.web.reactive.socket.client.ReactorNettyWebSocketClient of org.springframework:spring-webflux:5.1.6.RELEASE is :

public class ReactorNettyWebSocketClient implements WebSocketClient {

    private static final Log logger = LogFactory.getLog(ReactorNettyWebSocketClient.class);


    private final HttpClient httpClient;


    /**
     * Default constructor.
     */
    public ReactorNettyWebSocketClient() {
        this(HttpClient.create());
    }

    /**
     * Constructor that accepts an existing {@link HttpClient} builder.
     * @since 5.1
     */
    public ReactorNettyWebSocketClient(HttpClient httpClient) {
        Assert.notNull(httpClient, "HttpClient is required");
        this.httpClient = httpClient;
    }
  .....
}

It's second constructor above need a HttpClient object to instance, that mismatched with org/springframework/cloud/gateway/config/GatewayAutoConfiguration$NettyConfiguration.class.


@Bean
public ReactorNettyWebSocketClient reactorNettyWebSocketClient(@Qualifier("nettyClientOptions") Consumer<? super HttpClientOptions.Builder> options) {
    return new ReactorNettyWebSocketClient(options);
}

looks like a mismatch between maven artifact versions

This bug is documented on Github.

Here is one of the correct combinations of Versions that will work:
Parent:

<parent>
        <groupSId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.X</version> // I tested on <version>2.2.1.RELEASE</version>
</parent>

Cloud Version: <spring-cloud.version>Hoxton.RELEASE</spring-cloud.version>
