QBO not connecting to bank

Thanks for letting us know about this, pvma64.

I can share additional troubleshooting steps to fix the banking error you're experiencing.

The error code 105 occurs when there is ongoing maintenance on your bank or unable to establish a connection. This usually resolves within 24 hours. If not, you'll want to manually update your bank in QBO.

Here‘s how:

1. Go to the Banking tab.
2. Select the bank account and click Update.
3. If prompted, enter your Multi-Factor Authentication (MFA) credentials and select Continue update.
   
4. If you still can't connect, please wait 2 or 3 hours and try again.
