Thanks for reaching out to the Community. I'm here to ensure that your bank account is properly connected in QuickBooks Online.
You'll encounter Error 185 when your bank has extra security features when connecting. The system depends on the security protocol your bank has implemented to make it successful.
If I may ask, can you please verify the name of your bank? This is for me to further check the status connection of your bank account. To resolve this error you can run 3 to 5 manual updates on the Bank Accounts page. If you're ask to answer a security question, then enter your answer. However, if your bank asks for an OTP, get your OTP code and enter each time you see Error 185.

Let me know how it goes on your end. I want to make sure you're properly taken care of. Have a great day!
