Thanks for bringing this to our attention, BeiloonDB.
Error 176 means that QuickBooks Online (QBO) is unable to sync or update data from your bank servers due to the following reasons:
- Changes to your Online Banking Login credentials.
- Bank outages or scheduled maintenance.
- Updates on your bank website or account information, such as account numbers.
To confirm, log in to your bank's website to check if there are no issues with your credentials, security prompts, or account availability. Verify if their system is functioning accurately and not under maintenance.
If everything is fine on their end, we can manually refresh the connection between your bank and QuickBooks by following these steps:
- Go to the Banking menu in QBO.
- Select the affected bank or credit card account.
- Click the Update button.
If the issue persists, log in to your QuickBooks Online account using a private or incognito window and manually update the connection again. This helps rule out any browser-related issues. You can also switch to another supported browser to see if that resolves the issue.
If none of these steps work, you may consider uploading your transactions manually via a CSV file. For detailed steps, refer to this article: Manually upload your transactions, receipts, and bills into QuickBooks Online.
