I’m posting this to document an issue I’ve been trying to resolve with Human Interest and Quicken Simplifi.
For several weeks, I’ve been unable to connect my Human Interest 401(k) account in Simplifi. The error I consistently receive is:
“We are unable to connect to Human Interest at this time. Care Code: FDP-155.”
Troubleshooting already completed:
- Updated/retried the connection multiple times
- Deactivated and re-added the account
- Re-entered credentials
- Confirmed I can log in directly at Human Interest
- Removed MFA from my Human Interest account to rule that out
I contacted Simplifi support multiple times. Support confirmed that Simplifi uses Intuit as the data aggregator and that the failure occurs during the authentication/handshake phase, where the connection is being blocked by the financial institution .
Based on Simplifi’s guidance, I contacted Human Interest directly.
Here’s the key point:
Human Interest confirmed that they do not support third-party financial integrations (including Intuit/Quicken), and that this is a platform-level limitation — not an account-specific issue.
They also document this publicly here:
https://support.humaninterest.com/s/article/Can-I-integrate-my-Human-Interest-account-with-external-financial-software
The core issue
Human Interest is still listed as a connectable institution in Simplifi, but Human Interest states that third-party integrations are not supported.
Support’s current response has been:
- The bank is blocking the connection
- There is no escalation path
- Manual CSV import is the only option
- The institution remains listed because some accounts may still work
From a user perspective, that does not resolve the issue.
If Human Interest does not support third-party integrations at a platform level, then listing it as a supported/connectable institution is misleading and results in unnecessary troubleshooting.
Questions for the Simplifi team
- Is Human Interest officially supported in Simplifi today?
- If Human Interest does not support third-party integrations, why is it still listed as connectable?
- If only some legacy or partial connections work, can that be clearly communicated?
- Can this be reviewed by the product/integrations team rather than treated as an individual support issue?
- Should this institution be removed or clearly marked as unsupported if new connections are not functional?
I understand Simplifi cannot force Human Interest to allow aggregator access.
However, this is no longer just a connection issue — it’s a product accuracy issue. The platform is presenting an institution as connectable while the institution itself states it does not support integrations.
At minimum, users should not have to spend weeks troubleshooting something that may not be supported in the first place.
