myopenHAB service not working?

I was using the iOS app today from outside my house (through myopenHAB service) and it suddenly stopped working at around 14:30 (I swear I didn’t change anything and it suddenly stopped working).

At first, I thought it was my phone, but then I realized the openHAB application was marked offline on

Upon arriving home, I was able to use the iOS app through my local WiFi, but not anymore from a remote network. openHAB was, however, working properly.

I have uninstalled the myopenHAB service and re-installed it with the new uuid and secret, and although openHAB is now shown as “online”, the iOS app doesn’t work anymore outside my house.

I think there is a problem with the service, because there are errors in the log:

2021-05-01 20:12:07.442 [WARN ] [] - Token issuing failed: invalid_grant

2021-05-01 20:12:07.648 [WARN ] [io.openhabcloud.internal.CloudClient] - Jetty request 27884523 failed: HTTP protocol violation: Authentication challenge without WWW-Authenticate header

2021-05-01 20:12:07.649 [WARN ] [io.openhabcloud.internal.CloudClient] - Response Failure: HTTP protocol violation: Authentication challenge without WWW-Authenticate header

2021-05-01 20:12:13.289 [WARN ] [io.openhabcloud.internal.CloudClient] - Unsupported request method HEAD

Can anyone confirm me if the myopenHAB service is down or having troubles?

Myopenhab is working fine for me. No problems.


Then it looks it’s only me.
I don’t understand. It just suddenly stopped working.
What could it be and what can I do?
I can’t use openHAB outside my home now…

Try restarting the openhabcloud addon or openHAB. There is an issue where the cloud thinks your instance is offline while it is not:

It looks my iOS app went nuts for reasons unknown.
Restarting the openhabcloud did not help but, I re-installed it and the app worked again!
Thanks for your help.

Hi, its not only me, but there are some others too, that we have the problem, that after 4 or 5 days the cloud connector goes offline. It says, your openhab is offline, but its there. The problem can be fixed for the moment by going to Settings, Openhab Cloud, saving the not changed Settings. Then it works again:

Here are the log, when it goes online again:

2021-05-12 17:51:06.071 [INFO ] [io.openhabcloud.internal.CloudClient] - Shutting down openHAB Cloud service connection

2021-05-12 17:51:06.080 [INFO ] [io.openhabcloud.internal.CloudClient] - Disconnected from the openHAB Cloud service (UUID = ****, base URL = http://localhost:8080)

The problem is, when you are in front of your house with alarm system activated and you cant use openhab on your mobile device for deactivating your alarm system…

Has anyone an idea?

It is not working right now. The connection, I mean.
I cannot connect to openHAB from the outside, but I can connect from my WiFi network.
Does anyone experience the same?

Same. No The website doesn’t even load on a browser.

Din‘t you read this sticky?

No, I didn’t see it.


Thank you so much for providing this info.
