Which JDK are you using?
should give you the required information for us to be able to help you further.
Thx fo reply. My java version.
openjdk version "1.8.0_111"
OpenJDK Runtime Environment (build 1.8.0_111-8u111-b14-2ubuntu0.16.04.2-b14)
OpenJDK Zero VM (build 25.111-b14, interpreted mode)
Hmm… Sorry, I thought that maybe you were using an older version of the JDK which does not support the ciphers used by the https://telegram.org/ site.
Not very helpful comment: notification works for me, I just sent a message to my mobile from the OpenHAB2 installation build number 597, so it is not something in the OH2 software itself
You are using OpenJDK which is not recommended. Please change to Oracle Java and give it another try.
Thx for advice. Now my java version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) Client VM (build 25.111-b14, mixed mode)
And all work fine!
