Hello Community,

My developers use the IntelliJ IDE to develop, as our environment is 100% cloud, we use NPA to access the development environments. We use spring as a framework for our applications.

My error is the following for some endpoints I simply cannot connect using IntelliJ and spring. If I do a curl or telnet I can access the endpoint normally, only IntelliJ and spring can't. I have openVPN as redundancy and I don't get this error.

Has anyone had a similar problem?

Below is a simpler application that I can replicate the error

package ConnectivityTest;

import org.springframework.http.ResponseEntity;
import org.springframework.http.client.reactive.ClientHttpConnector;
import org.springframework.http.client.reactive.ReactorClientHttpConnector;
import org.springframework.web.reactive.function.client.ExchangeStrategies;
import org.springframework.web.reactive.function.client.WebClient;
import reactor.netty.http.client.HttpClient;

public class ConnectivityTest {
    public static <ObjeresponseEntityct> void main(String[] args) {
        HttpClient httpClient = HttpClient.create().wiretap(true); // wiretap(true) é opcional, usado para depuração
        ClientHttpConnector connector = new ReactorClientHttpConnector(httpClient);

        ExchangeStrategies strategies = ExchangeStrategies.builder()
                .codecs(configurer -> configurer.defaultCodecs().maxInMemorySize(1024 * 1024)) // Ajuste o limite de 1MB (1024 * 1024 bytes)
                .build();

        WebClient client = WebClient.builder()
                .clientConnector(connector)
                .exchangeStrategies(strategies)
                .build();

        String url = "https://xxxxxx";

        client.get()
                .uri(url)
                .header("Authorization", "Basic dGVzdDp0ZXN0")
                .retrieve()
                .toEntity(String.class)
                .block(); // Bloqueia a execução até que a resposta seja recebida

        ResponseEntity<ObjeresponseEntityct> responseEntity = null;
        System.out.println("Response Code: " + responseEntity.getStatusCodeValue());
        System.out.println("Response Body: " + responseEntity.getBody());

    }
}
