Hi @ManojkuSahu,

The error that you see is because the java trustore is missing the TLS certificate that is required to connect to port 8181 on the appliance.

Therefore, you will need to import your TLS server certificate into the truststore used by your JVM and after this, skfsclient should be able to connect to your FIDO server instance without a problem.

You can also view/download the self signed certificate used by SKFS using the following link:

https://docs.strongkey.com/index.php/skfs-home/skfs-how-to/skfs-operations/payara-questions/find-current-self-signed-certificate-used-by-skfs

You can follow the steps listed in the following link to import the server certificate into the client truststore:

https://docs.strongkey.com/index.php/skfs-home/skfs-how-to/skfs-operations/payara-questions/import-certificate-into-client-application-trust-store

Hope this helps !
