“Something unexpected happened and we can't connect to [bank].”

When you see these errors, it means there's something unexpected on the bank's end that we can't resolve. We're unable to know what the exact issue with your bank is, but recommend waiting a few hours to see if it resolves itself. After that, try to connect your bank again.
