Extension is working for importing product from Aliexpress

Hello,

This is Al Amin from Bangladesh. A month ago, I started using the plugin for importing products from Aliexpress but when reached 39 that I imported from Aliexpress, the extension is not working. As follows the product importing system, I did same like first adding domain and next secret key, then save. But now suddenly it shows me the problem – “Domain not resolved. Please enter correct domain and secret key that you set in Dropshipping and Fulfillment for AliExpress and WooCommerce plugin” Please help me to solve the problem.

I would really be grateful for your kind help. Thank you.

Regards,
Al Amin
