Have just started getting a problem using dataloader. I am running batch jobs that call dataloader which have worked successfully for a long time. I am now getting the following which I think is the problem (I have included the full message out put after):
Caused by: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
        at sun.security.ssl.SSLSessionImpl.getPeerCertificates(Unknown Source)
        at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.jav

I do not know of anything that has changed but this sounds to me like something needs to be generated but I have no idea how to go abut it. Any help would be appreciated.
