I am unable to add the Tiller Community Solutions Add On. I keep getting the error message: Access blocked: Tiller Labs Solutions is not approved by Advanced Protection.

It further says: The Advanced Protection Program performs additional security checks to safeguard your account data, and it hasn’t approved this app. This security feature stops most non-Google apps and services from accessing your data to keep your account protected.

If you are a developer of Tiller Labs Solutions, see [error details]

Error 400: policy\_enforced

If I click on the “Learn more about this error” link, here is what comes up:

## Error 400: policy\_enforced

Please help with this…thanks.

Hi Corey,

I found this post which basically states at the bottom of the link that the add-on will not work if the Advanced Protection is turned on.

Did turning off Advanced Protection help?
