Rampant CC-503 (invalid login credentials) errors on multiple accounts

WhySoSlow

Have been using Quicken for over 30 years.

Accounts I have previously connected, work until they are disconnected. Attempting to reconnect causes a cc-503 error

New accounts I try to connect, result in cc-503 error

Barclays. I have multiple credit cards under two different accounts. They have been working ok, and I have not disconnected them, and they continue to work. I just opened a savings account. Attempting to connect it using the same login as the credit cards of one of the accounts results in cc-503. I am still able to download already connected credit cards with this login and password. I can log in to Barclays website with the login and password

The same thing is happening with Sam's Club personal credit card. I was connected fine for years, I disconnected it, and when I try to reconnect, I get cc-503. I talked to Quicken Classic support, who said to contact Synchrony Bank. I reached Synchrony Bank tech support, who advised me that when attempts are made to log in via Quicken, they can see them on their system. They could not see any of my attempts.

Please advise and assist.
