CertificateException: No name matching <hostname> found.

I'm trying to access a web service that uses BASIC Auth + SSL with a self-signed cert. I've cobbled together code that should work, and imported the cert from the server into a keystore. I have verified that the CN for the crt is identical to the target hostname and matches exactly what CertificateException is telling me it needs. I've hit a brick wall here and would appreciate any assistance an SSL veteran can provide. Thanks!

and the certs in my keystore

Your cn name should match with your host name

Thanks. I am aware the hostname lab-nf-01.ns.cs.boeing.com must match the CN lab-nf-01.ns.cs.boeing.com.
They do, which is why the error is so frustrating and unhelpful.
