I am using aPuppet Premium in our corporate LAN with custom certificates.

I was able to deploy aPuppet web panel and it shows "Ready to Control", but mobile devices cannot connect to it:

java.security.cert.CertPathValidatorException: Trust anchor for certification path not found

How to fix the issue?

This issue happens if you specify a single HTTPS certificate in nginx settings (custom_ssl_cert parameter in config.yaml). You need to concatenate the whole chain of certificates into one file:

cat Certificate-website.pem CACertificate-INTERMEDIATE.pem CACertificate-ROOT.pem > CAchain.pem

and specify the absolute path to this file in config.yaml:

custom_ssl_cert: /path/to/CAchain.pem

More details about setting up a custom certificate in aPuppet Premium can be found in README.md.
