Unable to sign in “Oops", "Unknown Error" or “Check Internet Connection” message in Quicken for Windows
This is likely a temporary issue
In some cases, the "Oops" error is caused by a server outage and can be resolved by simply waiting and trying again later. This is a known issue and a solution is already in development.
If the issue persists
If you are still getting the error after 1-2 hours, make sure you are on the latest release of Quicken. For more information, click here.
You may also see these error messages if the internet connection is slow or unstable. In this case, we recommend trying again later, or contacting your internet service provider about improving your connection.
