I got my rachio controller about 3 weeks ago and has work great until this morning. I went to stop a scheduled water this morning and got the message “The request could not be completed. Please try again later.” I had to let the schedule finish on its own. Next I tried to manually turn a zone on with my phone and got the same message.
I tried to close app and restart and also unplug the controller to see if this would help and I still get the same message.
