I use the spring boot RestTemplate to make a json request to the public network IP, but it always displays disconnected and reconnected a minute later

Log as follows:

Looks like your target servers only accept TLSv1.2 connections you must make sure that your code is only performing connections with that protocol which it seems your code is not doing. Can you please check your logs ( debug mode ) and see what is version? What spring version you are using?

Something like should show in logs during handshake in debug mode...

.....SSLConnectionSocketFactory - Enabled protocols: [TLSv1]

How to configure TLSv2 is already answered in this thread How to enforce TLS1.2 to Rest client using Rest Template

in Short you can try

import javax.net.ssl.SSLContext;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

SSLContext context = SSLContext.getInstance("TLSv1.2");
context.init(null, null, null);

CloseableHttpClient httpClient = HttpClientBuilder.create().setSSLContext(context)
    .build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);
RestTemplate restTemplate = new RestTemplate(factory);
