| <p>when you are trying to use SSL to connect to ActiveMQ then the "certificate_unknown" error shows on the broker when the client doesn't trust the broker's certificate. On the client, I would see an error as well: "No trusted certificate found". </p> |
| |
| <h3>Fix</h3> |
| |
| <p>Make sure that you exported the broker's certificate (step 2 in <link><page ri:content-title="How do I use SSL"></page></link>) and imported it on the client into a truststore (step 4). If you did those, did you specify the javax.net.ssl.trustStore system property when you started your client VM? </p></div> |
