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 188.8.131.52-CA-linux32) (build 1.8.0_262-b19) OpenJDK Server VM (Zulu 184.108.40.206-CA-linux32) (build 25.262-b19, mixed mode)
Any more Ideas what I can do?
