I know there are a lot of subjects about this error I've tried a lot of things that are recommended to do in these subjects and nothing worked so I'm here. I use RestTemplate with JDK 1.8.0_291 and Spring boot 2.4.7. I'm on an enterprise machine so I need to pass through a proxy with basic auth and proxy-authorization. When I make a GET request all is good, I can pass the proxy and I have the result I want but when I try to make a PATCH request I take an error :
2021-07-09 11:04:24.565 ERROR 13808 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.client.ResourceAccessException: I/O error on PATCH request for "https://....": java.net.SocketException: Connection reset; nested exception is javax.net.ssl.SSLException: java.net.SocketException: Connection reset] with root cause

The part "SSL Configuration" was found in one of the many subjects that I've read. If you have any idea to help me please. Thank you!
EDIT : I've resolved my issue with a RestProxyTemplate :
@Component
public class RestProxyTemplate {
private static final Logger LOGGER = LoggerFactory.getLogger(RestProxyTemplate.class);
private RestTemplate restTemplate;
@Value("${proxy.host}")
private String proxyHost;
@Value("${proxy.port}")
private String proxyPort;
@Value("${proxy.user}")
private String proxyUser;
@Value("${proxy.password}")
private String proxyPassword;
@Value("${api.timeout}")
private String timeout;
@PostConstruct
public void init() {
this.restTemplate = new RestTemplate();
final int proxyPortNum = Integer.parseInt(proxyPort);
final int timeoutNum = Integer.parseInt(timeout);
final CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(new AuthScope(proxyHost, proxyPortNum), new UsernamePasswordCredentials(proxyUser, proxyPassword));
final HttpClientBuilder clientBuilder = HttpClientBuilder.create();
clientBuilder.useSystemProperties();
clientBuilder.setProxy(new HttpHost(proxyHost, proxyPortNum));
clientBuilder.setDefaultCredentialsProvider(credsProvider);
clientBuilder.setProxyAuthenticationStrategy(new ProxyAuthenticationStrategy());
final CloseableHttpClient client = clientBuilder.build();
final HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setHttpClient(client);
factory.setReadTimeout(timeoutNum);
factory.setConnectTimeout(timeoutNum);
restTemplate.setRequestFactory(factory);
LOGGER.info("RestTemplate initialized");
}
public RestTemplate getRestTemplate() {
return restTemplate;
}
}
And when I want to use my restTemplate I do that :
public class ... {
@Autowired
RestProxyTemplate restProxyTemplate;
public void method(){
RestTemplate rt = restProxyTemplate.getRestTemplate();
rt.exchange(...);
}
}
Thanks !
