Hi Jason, This happens when the OAuth token is expired for the device. In the IoTS alpha we have not implemented the renewing the token with refresh token part, however this has been implemented in the master. One way of having a continuous connection for the samples in alpha pack would be to increase the expiration time in identity.xml (repository/conf/identity/identity.xml).
