I know that you won’t be happy with my answer, but I would say “update your system to Java 11 and OpenHAB v3.4” … :wink:

3

Or update to 2.5.12 at least.

These are curious domain names to see

4

I just saw the same WARN messages in my logs, any idea what this might be ?

Hardware: Intel NUC - i7-6770HQ
OS: Ubunntu Server:22.04
OpenJDK Runtime Environment Zulu11.62+17-CA (build 11.0.18+10-LTS)
OpenHab: 3.4.2

Did you open a port on your router to get access to OH from the internet? Looks like one is trying to use your oh instance as a proxy.

6

Yes it’s a botnet trying to figure out if it can use your machine as a proxy, see also:

This is strange I do have a proxy (HAProxy) to forward https://openhab.xxxxxxx.com internally with a Let’s encrypt certificate but outside requests are blocked it should not be accessible from outside the local network. I do have port 443 open and other domain names like cloud.xxxxxxx.com will go to Nextcloud and plex.xxxxxxx.com will go to Plex server both on different internal hardware from the OpenHab server

I figure out what happened - I was doing network penetration testing when the warns happened.
