Why does QuickBooks Online show error 9999 and how do I fix it?

Error 9999 means QuickBooks Online lost connection with your bank for a second. A quick manual update usually fixes it right away. If it doesn't, a couple of simple steps will get your account back on track.

Here's what to try, in order:

1. Do a manual update. Go to All apps, then Accounting, then Bank transactions. Select Update. If that doesn't pull in your transactions, sign in through a private or incognito browser window and update again. That rules out browser extensions and cached sign-ins. Note that transactions older than 90 days can't be downloaded this way, so you'll need to add those manually.
2. Check your bank's website. If downloads seem slow or stuck, the issue may be on the bank's end. Sign in directly to your bank's website (not through QuickBooks) and look for any posted outage or maintenance notice, account alerts, or new security requirements. Bank-side outages usually resolve within 24 to 48 hours. Once everything looks clear there, go back to QuickBooks and select Update again.
3. Update your bank info in QuickBooks if anything changed. If you've updated your account number, username, or password on your bank's website, go to All apps, then Accounting, then Bank transactions, select the account card, then Edit, then Edit sign in info. Enter your updated bank details and select Save and connect.
