Continual ping timeout since mid-July 2026

Apps & Services openHAB Cloud
1

I am constantly seeing “Socket.IO disconnected: ping timeout” messages in openhab.log for CloudClient; this behavior just started within the past week or so, which is killing accessibility from my phone (IOS 26.5.2, App 3.3.8). Even when I can establish a browser connection to myopenhab.org, I see the same behavior within a minute.

I am running OpenHAB 5.1.4 on Linux Ubuntu 24.0.4 LTS with latest patches. I have a number of travel intervals coming up and I would like to have consistent remote access through the Cloud endpoint if I get an alert …

Is there any possibility that CloudClient connection stability is affected by client IP address changes? I also noticed that my ISP moved to a new public address block…
(grasping at straws)

It might be. I have the situation that we’ve changed the ISP at home and finally got Fiber internet, however the ping from my flat in my university city has increased a lot.
I did some debugging (traceroute and mtr) and I found out that my DSL provider in the flat doesn’t peer at IXP but only through a different ISP and the route from my flat to my home now goes through Sweden (I live in Southern Germany).

Maybe you can perform a traceroute to home.myopenhab.org or a normal ping to it from your network?

see below, with a few details masked; I guess I should expect a slower response if the packets must criss-cross the Atlantic :frowning:
