Java XMPP client Smack 4.2.4 why is there a "bad-auth/" error?

Question

Java

Hello everyone, I'm a beginner and found the following jabber client code on the net:

package jabberIL;

    import java.io.IOException;
    import java.io.BufferedReader;
    import java.io.InputStreamReader;
    import java.lang.InterruptedException;
    import java.net.InetAddress;
    import javax.net.ssl.HostnameVerifier;
    import javax.net.ssl.SSLSession;
    import org.jivesoftware.smack.ConnectionConfiguration;
    import org.jxmpp.jid.DomainBareJid;
    import org.jxmpp.jid.EntityBareJid;
    import org.jxmpp.jid.impl.JidCreate;
    import org.jxmpp.stringprep.XmppStringprepException;
    import org.jivesoftware.smack.tcp.XMPPTCPConnection;
    import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;
    import org.jivesoftware.smack.SmackException;
    import org.jivesoftware.smack.XMPPException;
    import org.jivesoftware.smack.AbstractXMPPConnection;
    import org.jivesoftware.smack.packet.Message;
    import org.jivesoftware.smack.chat2.ChatManager;
    import org.jivesoftware.smack.chat2.Chat;
    import org.jivesoftware.smack.chat2.IncomingChatMessageListener;

    public class JabberIL { 
        public static void main(String[] args) throws XmppStringprepException, SmackException, XMPPException, IOException, InterruptedException  {
            String msg;
            BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

            InetAddress addr = InetAddress.getByName("ip_server"); 
            HostnameVerifier verifier = new HostnameVerifier() {
                    public boolean verify(String hostname, SSLSession session) {
                        return false;  // false 
                    }
            };

            DomainBareJid serviceName = JidCreate.domainBareFrom("name_server.ru"); 
            XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()                    
                        .setUsernameAndPassword("name","pass") 
                        .setPort(5222)
                        .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                        .setXmppDomain(serviceName)
                        .setHostnameVerifier(verifier)                        
                        .setHostAddress(addr)
                        .setDebuggerEnabled(true)   
                        .setSendPresence(true)
                        .build();
            AbstractXMPPConnection conn1 = new XMPPTCPConnection(config);       

            conn1.connect();
            if(conn1.isConnected()){
                System.out.println("XMPP Connected");
            }   

            conn1.login();          

            ChatManager chatManager = ChatManager.getInstanceFor(conn1);    
            chatManager.addIncomingListener(new IncomingChatMessageListener() {
                public void newIncomingMessage(EntityBareJid from, Message message, Chat chat) {                
                    System.out.println("Received message: " + message.getBody());
                }
            });
            Chat chat = chatManager.chatWith(JidCreate.entityBareFrom("[email protected]"));
            while (!(msg = br.readLine()).equals("bye")) {
                chat.send(msg);
            }           
            //conn1.disconnect(); 
        }
    }

It works for example when connecting to jabber.ru (connecting, receiving, sending messages). But when I try to connect to my jabber server on the local corporate network, I get this error, I attach the full stacktrace:

When I take, for example, the Wime client, it also connects to jabber.ru without problems, but when I connect to my local server with it, a warning about a self-signed certificate comes out with a question to accept or reject it. Is it possible that the problem of my falling client is just this? or not? I understand that the problem is most likely trifling, but I still have a bad understanding of processes)))
PS I found a piece of code on the network, which, as I understand it, makes me simply ignore what is there with the server's certificate. Although I'm not sure if it's true. This is inserted into my program (in pieces in the appropriate places):

import jabberIL.X509_Trust_Manager;
import javax.net.ssl.SSLContext;
import java.security.SecureRandom;
import javax.net.ssl.TrustManager;

SSLContext Cur_SSL_Context = null;
    try	{
      Cur_SSL_Context = SSLContext.getInstance("TLS");
      Cur_SSL_Context.init(null, new TrustManager[] { new X509_Trust_Manager() }, new SecureRandom());
    } catch (Exception e) {
      e.printStackTrace();
    }

                .setSocketFactory(Cur_SSL_Context.getSocketFactory())

And the implemented X509_Trust_Manager class itself

package jabberIL;

import javax.net.ssl.X509TrustManager;
import java.security.cert.X509Certificate;
import java.security.cert.CertificateException; 

public class X509_Trust_Manager implements X509TrustManager {
    
    public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {		
  }
    
    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {		
  }
    
    public X509Certificate[] getAcceptedIssuers()  {
        return null;
    }
}

But in this case my program crashes with a timeout error:

Exception in thread "main" org.jivesoftware.smack.SmackException$NoResponseException: No response received within reply timeout. Timeout was 5000ms (~5s). While waiting for establishing TLS
