Spring Cloud Config Connect to spring-config-server from spring-config-client with https failed.

Hi Team,

I have created the config server with self-signed certificate. Now I am trying to connect config client (spring boot applicaiton in my local machine) but getting below exception 2016-09-08 14:11:39.270 WARN [csapi,,,] 7448 --- [ restartedMain] c.c.c.ConfigServicePropertySourceLocator : Could not locate PropertySource: I/O error on GET request for "https://localhost:9443/testapi/dev": java.security.cert.CertificateException: No name matching localhost found; nested exception is javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No name matching localhost found

Is there any way to overcome this issue in my local machine?

Thanks in advance.

Sounds like the certificate CN does not match the hostname, in this case localhost. You probably want to double check that your self-signed certificate is using the right CN and if not recreate it.

This article might be of some help: http://java.globinch.com/enterprise-java/security/fix-java-security-certificate-exception-no-matching-localhost-found/

Although this issue has been closed, i have one question. Will a client be able to connect to a config server using a self-signed certificate? Is the only requirement to match the CN in the self-signed certificate?

Yes, you might need to customize the RestTemplate though https://docs.spring.io/spring-cloud-config/docs/current/reference/html/#custom-rest-template
