Why Can't I Connect to My Server Despite Trusting Its Self-Signed Certificate?

Resolving "Unable to Find Valid Certification Path" Error Despite Trusting Certificate

Encountering the error "unable to find valid certification path to requested target" while accessing a server with a self-signed certificate can be a perplexing issue. Despite importing the certificate into the trust store, you may still encounter this error.

To address this, verify that your application server is configured to use the correct trust store. Different app servers may have their own trust store settings that may not automatically inherit from the system-wide trust store.

To isolate the issue, you can use debug flags to inspect the JVM's behavior. Run your application with the debug flag -Djavax.net.debug=all to trace all SSL-related events. You can set all to more specific values, such as ssl or keymanager, to control the granularity of the debug output.

By analyzing the debug output, you can identify if the JVM is using the correct trust store and if there are any additional errors or warnings. This will help you pinpoint the cause of the "valid certification path" error and resolve it accordingly.

Additionally, ensure a clear distinction between the keystore (used for your own identity) and the trust store (used to determine trusted certificates). Verify that the trust chain for both your server certificate and the certificates you trust are correctly established.

By leveraging these techniques, you can overcome this issue and establish a secure connection to the server using its self-signed certificate.
