Periodically, I get the error message "You're Offline. ..." on my Mac version of Evernote when, in fact, I am NOT offline. I have seen the KB article that says, "just reboot your computer" or "restart Evernote" as two of the suggestions. From a user point of view, this works, but is not satisfying because Evernote does not reopen formerly open cards upon restart (very irritating). This seems like a bug to me.
