Thanks for the prompt response, @accounting476.
I'm here to provide some details regarding the error and ways on how to fix this.
Several factors could cause error code 386, such as a typo, an outdated account number, or a system glitch.
Have you recently updated your account information on your bank's website, like your password, username, or account number? If yes, you need to update it in QuickBooks too:
- Go to Banking.
- Locate your bank account, then select the Edit ✎ icon.
- Click Edit sign-in info.
- Update your info as needed.
- Select Save and Close.
- After saving your bank details, click the update button located at the top right part of the banking page.
If this didn't fix your problem, I recommend contacting our Support team to ask for an update: QuickBooks Online Support.
