woocommerce_rest_cannot_view, Sorry, you cannot list resources, 401

I recently migrated my website from a cPanel host to a Virtualmin host.

Immediately upon transfer, my connection to a service called TradeGecko is failing with error: woocommerce_rest_cannot_view, Sorry, you cannot list resources, 401.

I cannot identify where the issue is stemming from.

TradeGecko staff told me to try out this utility: https://woocommerce-playground.herokuapp.com/.

The only way to get the utility to work and not result in the above error is using “Insecure Mode”

Help!!
