Anyone else getting reconnect error 750 when reconnecting to Citibank credit cards acct?

Hello @papercutsllc.got,

Thank you for reaching out to the QuickBooks Community. Let me share an update about the connection issue with Citibank.

The good news, the investigation for error 750 has been closed and resolved. Now, let’s do a manual update to refresh the connection between Citibank and QuickBooks Online.

For most banks, QuickBooks downloads the latest available transactions every night around 10 PM PT. Some may take a little longer. If downloads seem stuck, or you want the latest available transactions, do a manual download:

1. Go to the Banking menu or Transactions menu.
2. Go to the Banking tab.
3. Select Update.

This updates all your connected bank and credit card accounts. The number of transactions in each account tile will increase if QuickBooks downloads new transactions.
