I have openhabian installed on an Ubuntu machine. However when I try to use a plugin that connects to the internet like CalDAV or Pushbullet I get this error:
IO problems pushing note: java.util.concurrent.ExecutionException: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
Apparently it is a security problem and it was suggested to download the new jce policy jar files and exchange the old with the new one. However the error still appears.
I’m running this java version:
openjdk version "1.8.0_262"
OpenJDK Runtime Environment (Zulu 8.48.0.51-CA-linux32) (build 1.8.0_262-b19)
OpenJDK Server VM (Zulu 8.48.0.51-CA-linux32) (build 25.262-b19, mixed mode)
Do you try to connect to CalDAV service hosted on Pushbullet ( calendar.pushbullet.com ) ?
I have the impression that the problem is located at pushbullet.com.
Alright so, found my problem. It was on my end my DNS ad-blocker from pfBlocker-NG was causing the issues. I set a static resolvers in the /etc/hosts file for now until i get update pfBlocker-NG to whitelist pushbullet.com.
