Demo server connection refused

Hello,

I am totally new to openhab. I wanted to try the a android app, and when I use the demo mode, i get an error :

I have not installed my openhab personal server yet, so I cannot test with an other address…

Any help ?
Thanks

Would a test in a browser be sufficient ?
Try https://demo.openhab.org/

Hello,

Thanks for your answer,

This URL works well on the web browser. I have cleared cache of the openhab application but always the same error…

I get this error on both wifi and data networks. I am running android 10 on a galaxy S9… don’t know if these infos can help…
