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...
It works for me. It is a known bug and they are working on it. Just a few pages back in this thread...
It will become a non-issue as soon as more wallets integrate it in to their software. Not much the Trezor team can do about that.
