SSLHandshakeException Chain Validation failed

 javax.net.ssl.SSLHandshakeException:Chain Validation failed

The error "javax.net.ssl.SSLHandshakeException: Chain Validation failed" indicates an issue with establishing a secure connection between your application and a server using SSL/TLS. 

Validation chains are created by functions such as body() , param() , query() , and so on. They have this name because they wrap the value of a field with validations (or sanitizations), and each of its methods returns itself. This pattern is usually called method chaining, hence why the name validation chain.The javax.net.ssl.SSLHandshakeException: chain validation failed error usually occurs when there is an issue with the SSL/TLS certificate chain during the handshake process. This can be due to several reasons, such as an untrusted certificate authority, an expired certificate, or an incomplete certificate chain.

Here are some potential causes and solutions:

1. Server Certificate Issues:

• Expired Certificate: The server's SSL certificate might be expired. Check the server's validity period and ensure it's current.
• Untrusted Certificate Authority (CA): The certificate might be issued by an unknown or untrusted CA. You might need to add the CA certificate to your application's trust store.
• Incorrect Server Name: Double-check that you're connecting to the correct server address. The certificate might be valid only for a specific hostname.

2. Client-Side Issues:

• Outdated Java Runtime Environment (JRE): Ensure you're using an up-to-date JRE version that supports the latest security protocols and trusted CA certificates.
• Incorrect System Time: An incorrect system time on your device can lead to certificate validation failures. Set the correct date and time on your device.
• Incorrect Trust Store Configuration: The application might be using an incorrect trust store or missing necessary CA certificates.

Troubleshooting Steps:

1. Verify Server Details:
   • Check the server's SSL certificate expiration date using online tools like https://www.ssllabs.com/ssltest/index.html.
   • Confirm the server hostname matches the certificate's subject name.
2. Check Client Configuration:
   • Update your JRE to the latest version.
   • Ensure your device system time is accurate.
   • If possible, review your application's trust store configuration and ensure it includes the required CA certificates.

Additional Tips:

• Some libraries or frameworks might offer options to disable certificate validation for development purposes. Only do this in controlled environments as it bypasses security measures and leaves your application vulnerable.
• If the issue persists after these steps, consider contacting the server administrator for further assistance with their SSL certificate configuration.

SOLUTIONS:1

The error javax.net.ssl.SSLHandshakeException: Chain Validation failed typically indicates a problem with the SSL certificate chain or the domain's DNS settings not pointing correctly. We faced this isseus for Jyotishgher forecast-Mantra,Horoscopes and Consultations

Please ensure that your domain xxxxxx.in is correctly pointing to the IP address xx.xxx.xxx.xxx with an A record. Here’s what you should check:

• Record Type: A
• Hostname: @
• Target: xx.xxx.xxx.xxx
• TTL: Default

After updating these DNS settings, it can take up to 24 hours for changes to propagate and for the SSL installation to complete. Ensure these settings are correct in your domain registrar's panel. If the settings are already correct, just allow some time for the SSL to be fully installed.

Solution-2 Let's Hostinger  Panel

To disable the CDN and address the SSL issue, follow these detailed steps:

1. Log in to your Hostinger Panel: Access your Hostinger dashboard by logging in.
2. Navigate to CDN Settings: Look for the CDN option in the sidebar or search for "CDN" in the search bar.
3. Disable CDN: Once you are in the CDN settings, find the option to disable the CDN. This could be a toggle or a button. Click it to turn off the CDN.
4. Save Changes: Make sure to save any changes you made.

After disabling the CDN, try reinstalling your SSL certificate. If you encounter any issues during these steps, please let me know which step is causing trouble, and I'll provide further assistance!

Contact Admin and request for a renew of the SSL Certificate of your proxy url or base url you are using.

 Here are steps you can follow to diagnose and resolve the issue on Windows:

1. Check the Certificate Chain

Ensure that the certificate chain is complete and valid. You can do this by using tools like OpenSSL or an online certificate checker.

2. Import the Certificate into the Java Keystore

If the certificate is not trusted, you can import it into the Java Keystore (cacerts). Here’s how you can do it:

1. Export the Certificate:

   • Open the website or service in your browser.
   • View the certificate details and export it as a .cer file.

2. Import the Certificate: Open a command prompt as an administrator and run the following command:

   bash

   Replace <your_version> with your Java version and path_to_certificate.cer with the path to your exported certificate.

3. keytool -importcert -keystore "C:\Program Files\Java\jdk-<your_version>\lib\security\cacerts" -storepass changeit -alias your_alias -file path_to_certificate.cer

3. Verify the Certificate

After importing the certificate, verify it is added to the keystore by running:

bash
keytool -list -keystore "C:\Program Files\Java\jdk-<your_version>\lib\security\cacerts" -storepass changeit -alias your_alias

4. Check for Intermediate Certificates

Sometimes, the certificate chain might be missing intermediate certificates. Ensure all intermediate certificates are included and trusted.

5. Update Java

Ensure you are using the latest version of Java, as older versions might have outdated root certificates.

6. System Properties

Set the system properties for SSL debugging to get more detailed logs which can help in diagnosing the issue:

javae
-Djavax.net.debug=ssl

7. Environment Configuration

Ensure that your environment is correctly set up, especially if you are behind a proxy. Sometimes, SSL issues are related to network configurations.

8. Using Alternative SSL Library

Consider using an alternative SSL library like Apache HttpClient, which might handle SSL/TLS connections differently and could help bypass certain issues.
