- Issue of the topic:
I recently upgraded (sudo apt-get dist-upgrade) from 2.3 to 2.4.0.
The upgrade went fine and after the upgrade I just needed to install the MQTT add-on and configured it as per this link
and everything worked fine.
I mostly use the IOS OpenHAB app, and I started noticing a red bar on the bottom adding an error message.
In fact there are a few that pop up. It happens in at least every 10th time I use the app.
Error. Request failed, service unavailable (503)
And there is a (500) that also pops up. Sometimes the “sitemap” in my IOS app dissapears, like when the server is unreachable.
I saw a post https://community.openhab.org/t/clear-the-cache/36424
but it did not have any effect.
I am unsure how too troubleshoot this issue, as I don’t find anyting in any of the forums or groups.
Some assistance in troubleshooting will be appreciated.
