just restarted backend ... should be ok now
Yes, now it is OK.
But if you have to restart the server often, that might be an indicative that something weird is in the software.
Is the back end down again? Mine is just continuously just trying to pull of the transaction history again

This is a bummer that this is starting to happen more and more often. I was definitely telling everyone how great the trezor is. I still think it is, but reliability is definitely going to become a factor...
