Hi Elagold,

Thanks for posting in the Community!

Let me provide some information to help resolve your PayPal bank connection error in QuickBooks Online. 

Error 185 means your financial institution has additional security requirements you need to check like re-enabling the 2FA directly in your PayPal bank account.

Let's try to log-in to your actual PayPal Bank account then enable the two factor Authentication. Then, go back to QuickBooks Online and update the bank connection and see if it will go through successfully.

If the issue remains, please contact our Customer Care Team. That way, they can check your account in a secure form and check your account connection with our banking team.
