I'm trying to use WSS with LE certificate.  
I'm using node.js to setup the server. Everything is configured properly on the server (i think).

Using a WebClient like Chrome i can connect to the secure WebSocket, but i'm developing also an Android app that relies on the same server, but i get an expection:

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

I'm using Android Studio on OSX 10.11.3 - Java 8 build 71

Are you serving the chain with the Let’s Encrypt intermediate certificate? Did you configure the use of `chain.pem` or `fullchain.pem`, not just `cert.pem`?

Desktop browsers often don’t complain when the intermediate certificate is missing because they can cache it if they saw it on another site.
