Not getting a checkout window with subscription products

[ps-PKrueger]

I have started implementing this plugin on a woocommerce store with subscriptions. However, I haven't had any luck getting the Checkout to pop up. I get a flash of the wait icon, but then the pop-up closes without displaying the checkout.

I walked back through all of the Wiki instructions, recreated the ssl, regenerated an API password, and re-pasted the webhook (and re-verified that I had all of the events in the webhook, as well.)

I also made sure to create a product in both stores that had the same SKU and name, but still no pop-up check out.

If you would like to take a look at the store, it is available at https://perfectingsoftware.com/shop/

One other thing, I have turned debugging on, and am not getting a debug log when I check it is Woocommerce > Status > Logs. I see a few others, but nothing from the Fastspring gateway.

On the plus side, the plugin wiki was pretty clear, and the plugin back end walks you through everything that you have to do to get it set up. Thanks for that, it was a real help!

I discovered the issue. When placing the store name into the plugin, I copied it from the Fastspring site, complete with .test. in it.
When the test checkbox in the plugin is checked, it also adds .test to the address, so you get myname.test.test.onfastspring.com/storename. I removed the .test from the store name, and it is working. I will continue testing, and report on any issues that I come across.
