I followed this blog: http://evanthika.blogspot.com/2014/01/how-to-solve-pkix-path-building-failed.html I am trying to call this: curl -k http://localhost:8080/menu -H "Authorization: Bearer 265b7375-5411-3a56-8d00-00b34d6313f1" from this example: https://medium.com/@balaajanthan/oauth2-login-for-spring-boot-application-with-wso2-identity-server-da0a88893987
