I am determined to help you with your bank's connectivity issue. To do so, I may need additional information to give you a more accurate solution.
May I know what is your financial institution's name? Did you receive an error message/code? This way, I can check if there is an ongoing investigation under it?
In the meantime, we can try manually updating your bank account to refresh its connection with QBO.
Here's how:
Go to the Banking tab.
Select the bank account and click Update.
If prompted, enter your Multi-Factor Authentication (MFA) credentials and select Continue update.
Let me know how it goes. I'll be on the look out of your response. Please don't hesitate to leave me a comment below. Have a wonderful day ahead.
