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 must match the CN
They do, which is why the error is so frustrating and unhelpful.

You could try using a hostname verifier:
