Running a Managed Wordpress account via GoDaddy doesn't allow SellerChamp to connect to the WooCommerce API.
You'll have to reach out to GoDaddy and get a direct URL which will be used by SellerChamp to access the WooCommerce REST API.
If this is not the case, then please follow the proper steps in order to setup your WooCommerce store on SellerChamp.
There are certain configurations that need to be in place.
Click that link and it'll walk you through the setup.
If you're still facing issues, then please get in touch with us and let's schedule a meeting to get this sorted.
