Raspberry: After update to 4.0.2 mobile-desktop client are not able to login

Hello Gents,

I´m looking for a solution, hopefully this is a well known error, because I spent already some days:

After the upgrade from 4.0.1 to 4.0.2 my clients are not able to login to the software.

Spark is scanning for a search service and the mobile client has no sync to Openfire.
Spark is trying to connect every 12 seconds.

A successful login to the webinterface is possible and works fine.
BTW: Openfire runs at a RaspberryPi2 and Pi3.

From my perspective it looks like that the first handshake to the server works, but after this an unknown process failed.
Attached you find the screenshot of my spark. Wiederverbinden=Try to reconnect.

Thanks for supporting.

Best regards


I think I found the answer: Openfire 4.0.2 does not work with JRE 7.

So I try to replace JRE7 and upgrade this to JRE8 or provide a rollback to Openfire 4.0.2.


sorry additional problem occured.

I had already installed the latest JAVA version; here the evidence:

openjdk version “1.8.0_40-internal

OpenJDK Runtime Environment (build 1.8.0_40-internal-b04)

OpenJDK Zero VM (build 25.40-b08, interpreted mode)

and Openfire as service is as well already started, but I´m not able to see my login screen via browser.

Below the screen output of the started service:

best java alternative in: /usr/lib/jvm/java-8-openjdk-armhf/jre

Starting openfire: openfire.

What is wrong?

Thanks for supporting.
