"Error validating email," can't sign in to Evernote app on Mac

I've attached a screenshot of the error message I now get when I try to use Evernote desktop for Mac.

I can still use Evernote in my web browser, changed my password and it works. But some notes I took a while back are missing!!

I installed the latest update from the app store, it still didn't work, then I reinstalled the whole app again and rebooted my Mac and the same thing happens.

Can anyone help me please?

Same exact experience - can no longer get into the Mac app - I've reinstalled it and same problem happens.

It was my firewall settings. I have Little Snitch firewall, and something was being blocked that was preventing the app from working right. Sorry I can't be more specific.
