Problem routing to https://xxxxxxx. Error msg: SSL socket factory may not be null
One area where you may find this error is when consuming a service that requires a private certificate that is missing from the keystore. In such a scenario, you may also see "<key alias> in UNRECOGNIZED" in the "Select Private Key" dialogue box.
If you are using a ncipher HSM, a firmware update has also been known to address these types of issues.
