WooCommerce Parcel2Go plugin errors during installation

When installing it on my local development I have successfully mapped a domain using SmartSend and also added credentials for the WooCommerce client. However when I configure the client at /wp-admin/admin.php?page=parcel2go%2Fsettings.php
I see several errors and associated bad user experience with it

1 – look up for countries returns a 401 response see https://www.dropbox.com/s/922h28kcpkgwqzt/wooCommerceParcelToGo_CountriesNotLoading_2020-10-05_14-15-59.png?dl=0

The above is out of the box and given the error above the countries drop down is not loading.
