I have a new account with Fidelity for my new 401k. I have successfully added other Fidelity accounts to Quicken in the past (connection method for that account is Direct Connect and I have no issues downloading transactions for that one). Running Quicken Version R51.12, Build 27.1.51.12. I am able to start the add process, pick Fidelity Investments from the financial institution selection page, enter my account into, and click Connect. After that, Quicken reports it is looking up my account information for a couple seconds and then the Add Account dialog just closes. I have already tried signing out and back in to my Quicken account to no avail. My username and password are correct (copy/paste from my password manager). I do not know if this is a generic problem with Quicken or specific to Fidelity; I don't open new accounts terribly often. Any help to my specific scenario here would be greatly appreciated!
