you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. I'm wondering if it may not be letting you in because we're not using direct connect. Could you try adding the account again through the Wells Fargo Advisors connection then selecting advanced options instead of next > Complete investing > Direct connect. From there you should be able to try signing in again. This should be a different connection method than the one you tried with previously that should hopefully let us through instead.
let us know if this helps resolve the issue for you.
