Is there a problem with the Standard Bank connection? I have been trying to connect a few weeks, from different QB businesses, with no success?

Thanks for bringing this up in the QuickBooks Community, @chec64159.

I've checked our records and found an ongoing investigation about the error message you're getting. Our engineers are now investigating the error message you are experiencing when connecting with Standard Bank in QuickBooks Online. 

At this time, I encourage reaching out to our Support Team so you'll be added to the list of affected users in this investigation (INV-60875). Once added, you'll automatically receive an email notification with the latest updates.

For now, you can manually upload your transactions into QuickBooks using CSV file. This way, you can keep your accounts updated. Once the issue is fixed, exclude the downloaded transaction from your bank to avoid duplicates. 

 Once your transactions are in, it's time to match and categorise them.

Post again if you have any other questions. I'm always here to help. Have a good day!
