How to solve javax.net.ssl.SSLHandshakeException Error?

The javax.net.ssl.SSLHandshakeException error is usually caused by a problem with the SSL/TLS certificate of the server you are trying to connect to. This can happen if the certificate is self-signed or not trusted by the client, or if the certificate has expired or has been revoked.

To solve this error, you can try the following:

  1. Check the server certificate: Make sure that the server certificate is valid and not expired. You can use a tool like openssl to check the certificate and see if it is trusted by your client.

  2. Trust the server certificate: If the server certificate is self-signed or not trusted by your client, you can import the certificate into the truststore of your client. This will tell your client to trust the certificate and allow the SSL/TLS handshake to complete successfully.

  3. Use a different SSL/TLS protocol: If the server supports multiple SSL/TLS protocols, you can try using a different protocol to see if it solves the SSLHandshakeException error. For example, you can try using TLSv1.2 instead of TLSv1.1.

  4. Check for network issues: Make sure that there are no network issues that could be causing the SSLHandshakeException error. This can include firewall or proxy issues, or problems with the network connection itself.
