you for reaching out to the Community regarding your issue, although I am sorry
to hear that you are experiencing [issues with your program. It sounds like the program might not be responding properly to the server. If that's the case we may need to sign out and back in so that we're able to refresh the connection. You can do so by going across the top left to Quicken > Sign out. Once signed out sign back into your Quicken account.
Ideally once we're done signing back in we should be able to update without the error messages. Once
you get a chance to try these steps, please let us know how it goes!
