I appreciate you sharing the error code you've encountered, Valentina. This help's me identify the issue directly.

Error code 590 indicates that QuickBooks Online was unable to establish a connection to your bank account due to an unexpected issue on the banking side.

Since this has been going on for two months now, I highly suggest contacting our Live Support Expert team for further assistance with this matter. They have specialized tools that allow them to look directly at your account and can even conduct a screenshare session to help diagnose the problem.

In the meantime, you can manually upload your bank transactions into your QuickBooks Online account so you can continue reconciling your transactions and stay caught up while the connection is being fixed.
