We appreciate you for bringing this to our attention here in the Community, Krisha. One possible reason for the error message you're seeing could be related to a connectivity issue with the QuickBooks app. Let's work together to find solutions and get you back to managing your finances smoothly.
Before we continue, could you please let us know which specific version of the QuickBooks app you are using? This information will help us better understand your situation and provide you with the most accurate solutions.
Please take note that we no longer support the QuickBooks Self-Employed app. However, if you're using the QuickBooks Online app and have already cleared your cache, the next step would be to uninstall and then reinstall the app to ensure a fresh start.
Additionally, if the suggestions provided still do not allow you to log in, I recommend reaching out to our customer support team via our website browser and sign in using your QBO or QBSE account as a workaround. They have the expertise to conduct a thorough investigation of your account and will guide you through the next steps to find a solution.
