Samsung Gear S2 disconnects from Nexus 6P, Light Reset

If my Samsung Gear S2 gets disconnected from my Nexus 6P at all, I have to do a light reset and reestablish bluetooth connection with phone. I have tried updating the Gear Manager app, but I get "Unable to update new software. Device is encrypted. Decrypt?" It sends me to my security settings, but everything I have tried won't make it work.

Any suggestions???
