Citi Card Connection

MarcColety

Months ago I had the issue where my Citi Doublecash card no longer connected and when trying to reconnect the account I got a bad gateway error from the Citi side during connection.

The fix was to reauthorize the connection as a Costco Citi card (it isn't but it working).

Yesterday, each time I connected to an online download I would have to reauthorize the card again for the online connection.

Today, it won't reauthorize because it goes to a bad gateway on the Citi connect site after logging in. I had to do multiple online connections yesterday because of the Fidelity issues and now this…………

Anyone else having new issues connecting a Citi DoubleCash back card since 9/12/25?

Hello @MarcColety,

Thank you for sharing your experience. To help troubleshoot, please provide more information. There are a lot of different connection options with Citi; which connection option are you using when attempting to connect?

At what point in the connection process are you getting the Bad Gateway error? Which web browser are you using (Chrome, Edge, FireFox, etc.)? Do you use a VPN, anti-virus, or firewall?

I look forward to your response!

As of 9/13/25 11:00 pm EST, I was able to connect my Citi Double Cash card through the Costco Card link. As this has been connected this way before the last update, I am not yet confident it will work again tomorrow but for this moment in time, it is working again.
