Java CertificateException “No subject alternative names matching IP address … found”

Question

I\'m trying to implement a selfsigned certificate into my webserver, and it\'s working already with firefox and chrome (both from the server itself and from a remote machine

Answer 1

I have resolved the said

javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names matching IP address

error by adding one alternative subject name (DNS) in the server certificate (having CN=example.com) which after prints the part of certificate as below:

Subject Alternative Name:
DNS: example.com

I used KeyExplorer on windows for generating my server certificate. You can follow this link for adding alternative subject names (follow the only part for adding it).
