Hi @compumonk,
Are you seeing any specific error codes or any followup messages that may help us to determine what the problem might be? Can you confirm that you are trying "for the first time" to setup Quicken downloads for this credit card?
Also can you please explain what you mean by "Tried with MS EDGE, Firefox, and Chrome with the same result." - Exactly what were you "trying" to do that involves Quicken? Stared another way - what instruction were yoyu following in Quicken?
