Trusted TLS/SSL certificates
We do not support self-signed certificates. Your TLS/SSL certificate should be signed by a root certificate authority (CA) that is trusted by the default Java trust store. You can use the SSL Server Test from Qualys to check if your certificate is trusted by the Java trust store:
