Hi there!
This is Phil from the WooCommerce team. This thread was brought to my attention, so I wanted to add a post with a little more information in case other's find this helpful.
If you've already set up a Business Location in Square, but aren't able to select it when using our WooCommerce Square plugin the problem is likely in your hosting environment.
Here are the two common hosting issues that will cause this issue:
- If your host is blocking communication requests to either of the following endpoints, you won't be able to set your location:
https://connect.woocommerce.com/renew/square
https://connect.squareup.com/v1/me/locations
- If you (or your host) have not properly configured your SSL certificate, Square will be unable to authenticate your site during the connection process. This can result in the Business Location not populating.
- If your host has issues with cURL being improperly configured your site and Square will not be able to communicate
Typically the first two points are the most common and should be a quick fix for your host.
