Send Spring Boot simple email

I'm trying to send an email using Spring Boot. However, I get the error below in the console. I try the whole thing with GMX as email provider

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed: org.springframework.mail.MailSendException: Mail server connection failed. Failed messages: javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate); message exceptions (1) are: Failed message 1: javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)] with root cause

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

Main Code:

@Autowired
private JavaMailSender javaMailSender;


private void sendMail() {
    
     SimpleMailMessage msg = new SimpleMailMessage();
     msg.setTo("[email protected]", "[email protected]", "[email protected]");

     msg.setSubject("Testing from Spring Boot");
     msg.setText("Hello World \n Spring Boot Email");

     javaMailSender.send(msg);
   
}
