I use OSMC in its newest version on RPi 3. For controlling it I use Yatse Android app on my LG G4 which in turns makes use of standard HTTP service = web server that OSMC is presenting. In configuration I haven’t changed a thing, Chorus 2 UI is set, but for last month or two the web interface keeps turning itself off.
It happens irregularly once a day or two without any obvious trigger. Sometimes it works for a day and during the night, the server turns itself off. The next day OSMC cannot be controlled by Yatse. When I try to access OSMC web UI URL, it doesn’t work as well. When I connect my keyboard to the Pi at this moment, OSMC can be controlled and works smoothly so only thing stopping from work is web server.
Here are logs from today: my OSMC and remote control were working smoothly until lunch when the remote control turned itself off in middle of watching two videos. I restarted the Pi and the remote was back on.
Thank you for the response, I have edited my report.
Yes, I am using RPi 3 and for Android device I use LG G4.
However I think the issue won’t relate with Yatse as the web server with its UI is not accessible as well.
No I doubt if it’s yatse. There seems to be a problem with the rpi3 built in wifi and your symptoms seem quite similar, see this thread…
In my case it’s a samsung triggering the problem, I wondered if you were on a samsung too. My workaround is to use an external wifi dongle, do you have one you could try?
