I can help you connect your credit card accounts so you can get back to business, timschunk.
Firstly, you can visit your credit card website or reach out to your credit card support to check if everything's working on their end. This way, you can distinguish if they have server updates or maintenance preventing QB users from establishing new bank feed connections.
However, if everything is working on their end, I'd suggest linking your credit card account using incognito or other supported browsers.
Additionally, to provide you with the best possible solution, may I ask the name of your credit card account or if you encounter any errors? So that I can check if there are any reported cases on your credit card website.
Furthermore, here's a helpful article you can browse in case you need assistance getting the latest transactions from your bank and credit card accounts: Download the most recent bank and credit card transactions in QuickBooks Online.
