Shutting down openHAB Cloud service connection

Hi, I have been using openhab for a few years now and satisfied. Now I have switched to OH3. This is a clean installation on debian and I can’t connect to the openhab cloud. Below is a listing of debian, the openhab version - the apt package and the java version. Of course, I searched the forum, but the recommended steps don’t help, please don’t think of anyone? thank you very much Mirek

Please read the prerequisits. We strongly don’t recommend to uses OpenJDK Java, but Azul Zulu 11.
There are some issues with OpenJDK, leading to several problems.

thank you very much, so I’m going to try, I can’t install Zulu, so I chose this, unfortunately wrong. thank you MIrek

Why can’t install Zulu ?
Here are instructions for debian:

I follow exactly that, but in the end I have two mistakes:
Note: I select “zulu-repo” instead of “./zulu-repo_1.0.0-2_all.deb”

and then this one

openhab @ debian: ~ $ sudo apt-get install zulu11-jdk
Loading package lists… Done
A dependency tree is created
Loading status information… Done
E: Unable to find zulu11-jdk package

edit: instead sudo apt-get install zulu11-jdk works sudo apt-get install zulu-11 :wink:
