Gateway timeout cloud connector?

tldr; got gateway timeout, is the cloud service active ? or hints ?

just started with cloud connector on RPi -Zero which connect https://myopenhab.org/ with message " Your openHAB is online. Click here to access your openHAB’s dashboard"

My local openhab/java instance (lsof -i -P -n) is connected to :

  • java 15173 openhab 173u IPv6 103573 0t0 TCP *:8080 (LISTEN)
  • java 15173 openhab 88u IPv6 103600 0t0 TCP 192.168.x.xx:42830->172.104.246.157:443 (ESTABLISHED)

Inside openhab (openHABIAN 2.4.0) logs (tracing ) I see

2022-07-21 16:25:44.145 [DEBUG] [o.openhabcloud.internal.CloudService] - openHAB Cloud connector activated

Note: I can locally connect without problem and have restarted openHAB to be sure.

Cannot not figure out any cause on my end ?
Or should I expose my openHAB instance (which ports?) to the outside world ?

update: The cloud website https://myopenhab.org/notifications does receive explicit message notifications as executed by rules, f.e. by rules

  • sendLogNotification("sw010Switch.Test2 Changed to " + sw010Switch.state " at TimeAtStartOfDay "+ now )

You are aware that we do not recommend to run openHAB on a Pi Zero ?

Even you did not gave enough information about your system.

What OS exactly, what Java version?

Have resolved it myself, apparentely I overlooked the configuration settings to allow my instance for remote access …

Yeah, I know the recommendations but I like to pursuit what’s also possible.

Regarding your remarks, you’re right that things where not complete… FWIW, everyint works great, even as my openhab is way backward on 2.4.0. No problem as I (still) compile things myself, likewise as on my Qnap which is even more challenging.

pi@rpic:~ $ cat /etc/os-release | head -n 1
PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
pi@rpic:~ $ uname -a
Linux rpic 4.19.42+ #1219 Tue May 14 21:16:38 BST 2019 armv6l GNU/Linux
pi@rpic:~ $ java -version
openjdk version "1.8.0_332"
OpenJDK Runtime Environment (build 1.8.0_332-8u332-ga-1~deb9u1-b09)
OpenJDK Client VM (build 25.332-b09, mixed mode)

Note: to run cloudconenctor, I had to upgrade my Pi-Zero running standard Oracle java 1.8.0_65 to 1.8.0_332 via sudo apt-get install openjdk-8-jdk

Anyway things are solved… THX
