Title: Invalid authentication key Last modified: December 22, 2022 --- # Invalid authentication key * Resolved [customfit](https://wordpress.org/support/users/customfit/) * (@customfit) * [3 years, 5 months ago](https://wordpress.org/support/topic/invalid-authentication-key/) * Hi, * I temporarily copied my original site to a subdomain for testing purposes. I noticed the authentication key was different than on my original site. Then I migrated my original site to another web hosting. * Shipstation stopped working and the products are not getting imported anymore. The logs were not created until I deleted the shipstation plugin from the subdomain. There is a new log on the newly migrated site as of today: 12-22-2022 @ 12:22: 00 Invalid Authentication Key. * If I compare the authentication keys on the website and the Shipstation and they are different, would I just change it in the Shipstation account? Would it mess up the already imported products or import them again? * Please advise how to get it working again. * Thank you Viewing 3 replies - 1 through 3 (of 3 total) * [xue28 (woo-hc)](https://wordpress.org/support/users/xue28/) * (@xue28) * [3 years, 5 months ago](https://wordpress.org/support/topic/invalid-authentication-key/#post-16314917) * Hi [@customfit](https://wordpress.org/support/users/customfit/) * Thanks for reaching out! * I understand that after changing the hosting environment of your site, the plugin stopped working and produced the error message: `Invalid Authentication Key.`, is that correct? * The **Authentication Key **is a unique key that you’ll use when connecting your store to ShipStation. * You mentioned that the Authentication Key on your site and on your Shipstation account is different, please follow the steps here on [How to change the Authentication Key](https://woocommerce.com/document/shipstation-for-woocommerce/#how-to-change-the-authentication-key). * Let us know how it goes! * Thread Starter [customfit](https://wordpress.org/support/users/customfit/) * (@customfit) * [3 years, 5 months ago](https://wordpress.org/support/topic/invalid-authentication-key/#post-16342505) * Hello, * Disconnecting and reconnecting the Shipstation with woocommerce with a new Authentication key worked.
