Hello there, headnanny,
Make sure to turn off your browser's pop-up blocker while connecting your bank. This is to make sure that all contents of the pop-up window is displayed. Use the steps in this article on how to turn it off: Enable pop-up windows.
If the error persists, I recommend contacting our QuickBooks Self-Employed support. They'll be able to check the error you're getting and provide a resolution.
You also have an option to import your banking transactions using a CSV file if you're still getting the same issue. Here's how:
- Go to your bank's website and download a CSV copy of your banking transactions.
- Once done, go back to QBSE and click the Gear icon.
- Select Imports.
- Click Import older transactions.
- Click Browse and look for the file.
- Click Continue.
Once imported, you can proceed to assigning categories to your transactions.
Here's an article as a reference: Categorize and edit transactions in QuickBooks Self-Employed.
Let me know if you need anything else.
