When I try to reconnect my bank I keep getting a screen saying it’s failed. Any clues? Been trying for days

I’d be happy to help you reconnect your bank account to QuickBooks Self-Employed, @Gemma5.

May I know the specific bank you're trying to connect in QuickBooks? Or did you encounter an error message? So I can identify the root cause of this issue.

For now, you can try reconnecting your bank using a private browser to help us determine if this is a browser-related issue. You can use the shortcut keys below:

• Ctrl + Shift + P (Firefox).
• Command + Shift + N (Safari).
• Ctrl+ Shift + N (Google Chrome).

If you're able to connect your bank using a private browser, you may need to clear the cache of the regular browser you're using because when you visit different sites, it keeps the files on your cache browser so you can easily load the pages next time. If the cache is holding too much data, it can affect the browsing performance of the currently opened sites like QuickBooks Self-Employed.

You can also use other compatible browsers. It could be that the one you're currently working on has a temporary issue with QuickBooks.  

Please keep in touch with me here for all of your QBSE needs. I'll always have your back. Keep safe.
