Possible solutions

Configure maxIdleTime on the ConnectionProvider

ConnectionProvider connectionProvider = ConnectionProvider.builder("custom")
    .maxIdleTime(Duration.ofSeconds(60))
    .build();

HttpClient httpClient = HttpClient.create(connectionProvider);

WebClient webClient = WebClient.builder()
    .clientConnector(new ReactorClientHttpConnector(httpClient))
    .build();

Set Timeouts on the HttpClient

HttpClient httpClient = HttpClient.create()
    .option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 10000)
    .responseTimeout(Duration.ofSeconds(60));

Disable TCP Keep-Alive

HttpClient httpClient = HttpClient.create()
    .option(ChannelOption.SO_KEEPALIVE, false);
