I am on Classic Deluxe R53.16 Build 27.1.53.16. For the past week or maybe more I have not been able to connect after changing the password on the Alight site and then changing Quicken to match the same. The password works on Alight's website. Looks like similar reports exist while searching Quicken Community over the last year or so. Not sure how they got resolved. The error code is OL-332-A (The customer ID or password you entered does not match the information on file with your financial institution).
