Warning: Your last online connection was not completed

I appreciate you using QuickBooks for a long time, @Wizard. I've got steps to ensure we can get rid of the prompt when connecting bank feeds.

This pop-up message appears when you download transactions or send payments in the Bank Feeds Center. Before proceeding to troubleshoot, I recommend backing up your QuickBooks Desktop company file. This will help you save a copy of your accounting data for future use.

Since you've already contacted your bank to verify their status, let's find out which payments are stuck by  switch to register (classic) mode, if required.

Here's how:

1. Go to Banking.
2. Select Bank Feeds then select Bank Feeds Center.
3. From the Bank Accounts list, choose the account with stuck transactions.
4. In the Send items to your bank section, uncheck all online checks and bill payments to be sent.
5. Select the first payment, then select Send Items.
6. Repeat step 5 for each online payment until the stuck transaction is found.
7. When you've identified the stuck online payment, continue to clear stuck online transactions.

After that, follow the steps below to successfully clear the transaction:

1. Hold the Ctrl key on your keyboard and select Send/Receive or Sync Accounts..
2. Continue to hold the Ctrl key through the entire Online Banking session, except when you need to enter your user ID, password, or PIN.
3. The message "Your last online connection was not completed. QuickBooks Desktop is having a problem recovering from this condition" appears.
4. Continue to hold the Ctrl key and select OK.
5. The message "Do you wish to resend this request again to your financial institution, do it only after speaking to the Online Banking Technical Support." appears.
6. Continue to hold the Ctrl key while you select OK.

If the payments show as paid at your bank, and are listed in the queue, proceed to Solution 2 on this article: Error OL-200, OL-202, OL-206, or OL-226: Your last online connection was not completed.
