I sent you a link to the logs in a PM. It seems to be resolved with pr3.
I have also been having some odd issues with my S1 sometimes showing as offline (even when it isn't).
This is probably to do with the timeout set in MultiMiner for getting responses from Network Devices. My S1 can take over a second sometimes to respond which is more than my current timeout.
My plan is to up the timeout and make the calls async so this should be more consistently reported in a future update.
