SSl Tutorial application access issue

[lodhipr]

**Hi I have taken guidance to implement the code from: https://www.baeldung.com/spring-boot-https-self-signed-certificate

and have built two different applications in spring boot, one that exposes the endpoint and another is trying to connect it and retrieve the data but while testing I am getting an error, please give me a guide to resolve the issue**

Hi,

Most probably this StackOverflow thread should help you: https://stackoverflow.com/questions/50928061/certificate-for-localhost-doesnt-match-any-of-the-subject-alternative-names

Anyway, we'll double check the article and maybe update it so that it's clear how to test it locally.
