Hi there, rajat.k. Did you encounter a specific error message while linking your bank account to QuickBooks Online? If so, please let us know the error code or description so we can investigate further and provide a tailored solution.
In the meantime, ensure you have a reliable internet connection. A slow or unstable signal may prevent QuickBooks from communicating effectively with your bank.
You might also try entering your credentials manually. Sometimes QuickBooks has difficulty processing saved or pasted information, and manual entry can bypass these login errors.
You can also check your bank's website for any maintenance alerts or service outages that might be temporarily blocking the connection to QuickBooks.
If the automated sync fails, you can manually upload your data. Log in to your bank’s website, download your transactions in a .qbo or .csv format, and import that file directly into QuickBooks.
If you’ve followed these steps and are still having trouble, it’s time to reach out to QuickBooks Support. We can take a closer look at your specific connection and help resolve the issue.
