Hello @gregory
Thank you for reaching out on the community and telling us about your issue. I was taking a look and noticed that citi bank doesn't offer Direct connect which is generally where 209 errors come from. What troubleshooting steps have you tried previously? Did you recently switch from a different version of quicken as well? How long has this also been persisting?
Last thing here could you double check what connection method you're using. You can do so by right click on the account under the account bar and select edit/delete account. You'll get a small popup and across the top it will say online services. From here it'll have a small line saying your connection method.
Once we're able to gather a bit more info we'll see what our next step to troubleshooting will be!
Thanks,
Quicken Francisco
