Failed to generate Critical CSS (Jetpack Boost)

Hello, I am trying to use Jetpack Boost (free edition, evaluating before upgrade) on my site at happyroster.com – I keep getting an error “Failed to generate Critical CSS (Jetpack Boost)” and then Jetpack Boost couldn’t verify this page:
https://happyroster.com

This page is a legit page, but is being fed by a landing page plugin, SeedProd – could this be the issue?

Thank you!!
