Hi AEM Community,
I have a problem sending an HTTPS requests from my AEM instance to other endpoints. If I send an HTTP, then everything is fine, but when an HTTPS then I got an exception:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
http://mysite.com/blog/get - is fine
https://mysite.com/blog/get - throws an exception
Thanks for your help in advance.
For Self signed certificate you can follow the steps under "Generating a Private Key/Certificate Pair to Use with the Wizard" at 
On a live system, the certificate should be provided by your IT team
 SSL By Default
So, could you please tell, how can I set up my certificate?
You can check if your certificate is in the Keystore by running the following command:
keytool -list -keystore "%JAVA_HOME%/jre/lib/security/cacerts"
Looks like AEM is not able to find the valid certificate for the https request. Make sure the certificate is valid. Also, Have you tried the SSL By Default setup?
