Can't connect any new devices

I have been adding new devices over the past few days with no issues. However this afternoon I haven't been able to add any new devices. The app is never able to find the device that is clearly powered on. I've tried with two of the solar pathlights and one motion sensor. Nothing. I've also tried connecting with 2 different phones (both Android).I currently have 10 devices connected to my bridge (8 solar pathlights, 1 PAR bulb, and a mailbox sensor). I am able to turn them on and off via the app.
