Yet another habpanel crash on fresh OS and OH3 install and no bindings

http://my-local-server-ip:8080/habpanel gives me:

Connection lost! Trying to reconnect…

This is a fresh Ubuntu 20.04 LTS desktop install on VMware workstation pro 16 without any modifications other than installing open-vm-tools and a change in hostname

Here are all the commands i used to install OH3 and Mosquitto

sudo apt-get install mosquitto mosquitto-clients
sudo service mosquitto restart

sudo apt-key adv --keyserver hkp:// --recv-keys 0xB1998361219BD9C9
sudo apt-get install ./zulu-repo_1.0.0-2_all.deb
sudo apt update
sudo apt-get install zulu11-jdk

wget -qO - '' | sudo apt-key add -
sudo apt-get install apt-transport-https
echo 'deb stable main' | sudo tee /etc/apt/sources.list.d/openhab.list
sudo apt update
sudo apt-get install openhab
sudo systemctl daemon-reload
sudo systemctl enable openhab.service
sudo systemctl start openhab.service
sudo systemctl status openhab.service
openhab-cli info

Then i visited the openhab http://my-local-server-ip:8080/ just setup my location and did NOT install any bindings.

Here are all the contents of /var/log/openhab.log

homeserver:/var/log/openhab$ cat openhab.log

Note: I Tried the installation using openhabian at first and it gave me the same issue.

I can’t even find anything in the log to guide me where to look. The only WARN in the logs above is due to the browser trying to contact openhab during restart when it was not yet ready.

Can you please assist? All the other threads spoke about binding issues, and / or map transformation issues, etc… but I have 0 bindings and 0 map transformations listed in those sections

Apparently that’s not how you do it in OH3. You have visit the following url:

Or by going to : http://your-ip:8080/#!/ then selecting the icon on the top right for additional application then selection habpanel.

I will keep this post and not delete just in case someone else might find it useful.
