We can't connect to Commerzbank since 21 June with the message "We couldn't complete your connection. Try again or go back to select a different account provider (571)

You've come to the right place for assistance, bkim. I'll help ensure your online banking account is connected to QuickBooks Online (QBO) so you can manage your financial accounts.

Banking Error 571 happens when you have either closed the consent page when connecting your bank to QBO. Or, your web browser may have pop-up blockers enabled, which affects the completion of setting up bank connectivity.

To resolve this error, turn off the pop-up blockers on your web browser, then reconnect your bank. Once done, please refresh the page to allow the setup to load completely.

In case you're still unable to link your bank, you can manually upload your bank transactions to your QBO account as a workaround. To do this, you'll need to download the entries from your bank's website in a CSV file format.

Once ready, import these transactions to QBO:

1. In your QBO account, go to Transactions and select Bank Transactions.
2. Click on the blue tile for the account you want to upload the transactions into.
3. Select the Link account▼ dropdown and then Upload from file.
4. Choose Drag and Drop or select Files and select the file you downloaded from your bank. Then, select Continue.
5. In the QuickBooks Account▼ dropdown, click the account you want to upload the transactions. Then, Continue.
6. Follow the onscreen steps to match the columns on the file with the correct fields in QuickBooks.
7. Once done, select the transactions you'd like to import and select Continue.
8. Then, click Yes.
9. When you've accepted your transactions, select Done.

Additionally, here's an article that can help you find missing downloaded and previously categorized transactions: What to do if you can’t find downloaded transactions in QuickBooks Online.

Once everything looks good, you can start categorising your entries, then reconcile your account to ensure they always match your bank and credit card transactions.

If you require any additional assistance with bank connectivity, feel free to leave your queries in the comments below. I'll be available to assist you further. Stay safe.

We don't have pop-up bloker. Actually we viewd the "Consent to connect for 180 days" pop-up and clicked the "Agree" button on that. Then we receive the Error 571.

Try opening your QBO account on any private/incognito browser.

I appreciate that you've taken all the steps provided, @bkim_gitauto.

The Banking Error 571 occurs when you close the consent page while connecting to Open Banking in QuickBooks or when active pop-up blockers in your browser prevent the process from completing the banking connection.

Please let us know if you have other questions about banking concerns. I'll be around to assist. Stay well.

 I contacted call center but I am not sure they ascalated the issues to the Technical Support team. I didn't received a mail. One thing I curious is that our audit log says that "Automatically updated Online Banking accounts for Commerzbank - Unternehmerkunden und Privatkunden (Deutschland) (deleted)" by a user named "ONLINE BANKING MANAGEMENT" which is not our user.

Already tried that. And we had no effect.

I recognize the importance of having a seamless connection with your bank, bkim. Your concern is valid, and we want to help you get in touch with the right support team to help you with your banking issues.

Currently, we have identified that the issue you have encountered with connecting to Commerzbank and its associated error is linked to an ongoing investigation that we're working on. Please be assured that our engineering team is actively working to resolve this issue, and we anticipate providing you with an update soon.

In the meantime, you can consider manually uploading the bank transactions to your account, ensuring that the file format and size are suitable for successful import.

While we do not have a specific resolution date, I recommend contacting our QuickBooks Online Support team and requesting to be added to the list of affected users. This way, you’ll receive timely updates directly on the issue via email.

Here's how to reach a live representative:

1. Log in to your QBO company, then go to Help (?).
2. Click on Search, then Contact Us.
3. Enter a keyword or phrase related to your concern.
   
4. Choose to Chat with us to connect with us.
   

Once the connection is established, you'll want to exclude the bank transaction that appears to be the same to avoid duplicates.

If you have further questions about bank connections in QBO, please don't hesitate to reach out. We, in the Community, are always available to help.
