Hey there,
OH: 2.5.1-2
First, my Openhab runs with the roller shutters now for 1 year… soo it’s been working for a long time now.
My Problem is, I tried to control my roller shutters via the amazon echo app anyways the percentage bar began toggling so the values toggle between 50 and 0 luckily my roller shutter go into error mode… don’t know what happened when he would follow the commands 
Anyways, after this toggle action, I get a disconnect from the openHAB Cloud
What did I try?
I tried to restart and check my files…
Everything looks fine…
Is it possible that I get automatically get kicked?
Because of this toggle signal… maybe looks like DDOS for the System?
I really don’t know what to do now, I found some topics where they never got it running and reinstalled everything… I hope someone got an idea or can help
