Mirth certificate problems

[sdpillar]

I have a 2.2.3 installation of Mirth that utilises certificates to connect to a server.

The private key and the signed client certificate has been added to a certificate chain, which has been installed as the Mirth truststore.jks file.

However I get the following error when running through a java function called from Mirth:
