Yep... "Quicken cannot connect to this account" error on all ML accounts. (Quicken Mac Premier 6.5.1)
Same issue for me. Failing on all ML accounts. Using Quicken 6.5.1, Build 605.42638.100
I am ditto on this error as many of the above. Quicken Deluxe for Mac, V6.5.1 (Build 605.42638.100) & Mac OS 12.1, Getting Download Error (500), HTTP-500 Error from Merrill Lynch Investments. Quicken cannot connect to this account. My connection type is Direct Connect. On the Account Status screen I'm getting the same error for all four of my Merrill Lynch accounts. I've tried "Retry" many times but error keeps returning.
