I am unable to fetch bank transactions in QBO, when I put my login credential it's showing error 106. Please resolve these issue asap

I'd be delighted to get you moving in the right direction to bringing your bank transactions into QBO, @useraccounts-pune.

Banking error 106 comes into sight when QuickBooks fails to locate your account on your bank or financial institution's website. This situation arises when the account is closed, or QuickBooks Online is not able to discover the account. This information is available from our guide on fixing bank error 106.

Do you mind sharing your bank's name? We've also received reports from other users about error 106 when connecting their particular bank to QuickBooks Online. Our engineers are all hands on deck to get you back on track.

In the meantime, you can upload the transactions manually to ensure the account is up-to-date. Download the data from your bank then map the transactions in the following supported formats or file types:

• Comma-Separated Values (CSV)
• QuickBooks Online (QBO)
• Quicken (QFX)

Once downloaded, here's how to start your upload if you've connected your account to online banking:

1. Go to the Transactions or Banking menu. Then, select the Banking tab.
2. Click the blue tile for the account you want to upload the transactions into.
3. In the Link account drop-down menu, select Upload from file.
4. Click Browse and select the file you downloaded from your bank, then click Next.
   
5. From the QuickBooks account drop-down menu, select the account you want to upload the transactions into and click Next.
6. Click the QuickBooks account drop-down menu and select the account you want to upload the transactions into. Then, click Next.
7. Follow the onscreen instructions. Match the columns on the file with the banking fields in QuickBooks, then select Next.
8. Select Let's go.
