Hi there, sg4.
The error 590 occurs if your Financial Institution updated their bank's website. You're able to fix this by updating the login information in QuickBooks Online (QBO).
Here's how:
- Go to the Banking menu.
- Choose the bank tile and at the upper-right, click the pencil icon.
- Select Edit sign-in info.
- Enter your user ID and password.
- Click Save and connect.
Once resolved, go to the For Review tab to review your transactions. For more details, check out this article: Add and match downloaded bank transactions.
However, if the error persists, I suggest reaching out to our QuickBooks Support Team. They have tools like screen-sharing that will help check the root cause and find a permanent solution to this issue.
