Can you verify the name of the bank account you are trying to connect to? That information will help me provide a timely solution. Also, I suggest reaching out to your bank to check if they have any maintenance updates. Let's also make sure that you enter the correct credentials when connecting your bank with QuickBooks.
In the meantime, let's perform some troubleshooting steps to isolate the issue. To start, let's open your QBO account using incognito mode. This unexpected behaviour can be caused by too much cache that has been corrupted or damaged. The following are the shortcut keys you can use depending on your browser type:
Google Chrome: press Ctrl + Shift + N
Mozilla Firefox and Microsoft Edge: press Ctrl + Shift + P
Quick books aren’t letting me connect with my bank. It was fine before but now when I go to reconnect it says authenticationFailedINPUT. Very annoying. Any ideas?
Thanks very much for your quick reply. I am with the royal bank of Scotland. I can go through everything where it selects the account with the bank and says it’s approved then when it goes to take me back to QuickBooks it says it’s failed. This is all from my phone so I can try from my laptop tomorrow with what you have suggested. I have attached what comes up when it goes from my bank to QuickBooks. Thank you
