How did you add the certificate (note, that it has to include the private key, too) into your (configured) keystore? Can you list the entries in the keystore and show it to us? For example, when I use the keystore for RMI that can be generated by a shell script in the bin folder, I would use the following command and expect some output like $ keytool -list -keystore bin/rmi_keystore.jks Enter keystore password: Keystore type: PKCS12 Keystore provider: SUN Your keystore contains 1 entry rmi, Jan 23, 2018, PrivateKeyEntry, Certificate fingerprint (SHA1): D7:E4:FA:61:8F:52:8D:BA:09:10:D5:4F:F1:21:C6:AA:5C:10:0D:38 The alias of the client certifficate (Note the PrivateKeyEntry) is "rmi". If you want to use the KeyStore Configuration, that value (rmi) has to be put into a variable (for example "cert_name") and the string "cert_name" would have to placed in the KeyStore Configuration field "Variable name holding certificate alias". That configuration is meant to be used, if you have more than one alias (read key/certificate) in your keystore and want to change the usage of the certificate based on variables in the plan. If you have only one certificate, that might be a bit overkill. Also note, that the KeyStore Configuration is meant to be used with the HTTP Sampler from JMeter (especially the HTTPClient 4 implementation). Make sure, that it works with your sampler (by asking the third party plugin developer?).
