I appreciate you for posting this issue, kelly31.

I'm here to share how you can connect your bank to QuickBooks Online.

Since Nedbank blocks QuickBooks permission, you can reach out to Nedbank's support to allow the connection.

At this time, Nedbank hasn't told us when they'll begin allowing these connections again. If the issues remain unresolved, ask your bank representative to escalate the case through our OFX Connectivity page (English only) for resolution. 

As a workaround, you can upload your bank transactions into QuickBooks Online using WebConnect. Here's an article as your guide: Manually upload transactions into QuickBooks Online.

Afterward, you can categorise them to their correct accounts.

I'm just a post-away if you need help in uploading the items. I've got your back!
