HTTP Error Code 401

  • Hello! Hope you all are well.

    I’m currently setting up a new Printful + WooCommerce store, I’ve had success in the past doing so but on an Apache-hosting framework. This time however, I’m setting it up on a VPS running NGINX (.htaccess and rewriting rules work differently).

    Whenever I try to connect the Printful plugin to the WooCommerce site, I receive an error saying “Could not open Woocommerce authorization page (HTTP error 401). Make sure https://nullhypothesisrejects.com/wc-auth/v1/authorize is accessible.

    I’ve scoured the internet and I’ve tried the following things with no luck:

    • Switched to a default WordPress theme and disabled all plugins except WooCommerce and Printful
    • Ensured WooCommerce Legacy API is on, deactivated both plugins and activated WooCommerce then Printful sequentially to ensure proper generation of necessary config files.
    • Increased WordPress RAM usage to 1024M (1GB) and disabled UFW rules to ensure VPS-side network security is not interfering with the plugins.
    • Verified https://url-site/wc-auth/v1/authorize exists, leading to an expected “Error: Missing parameter app_name.”when visited through a web browser.
    • Ensured URL on Printful, WooCommerce, and WordPress settings are the same.
    • Manually added the API key from Printful.com onto the plugin, it seems to connect but 3 other issues pop up relating to fetching new data from Printful.com
    • Ensured WordPress permalinks are set to /%postname%/ and work.

    If you need additional data to diagnose, do let me know.

    I appreciate any help.

    Below is a dump of the logs:

    WooCommerce reports no error logs, only a test-log and a wc-image-regeneration log is found.

  • Hey! Sorry to hear that you’ve been running into some issues when connecting your Woocommerce store with Printful. The error you’re describing is usually caused by a web server configuration, WordPress configuration, or by a security plugin that doesn’t allow us to connect to your store.
    Firstly, it would be suggested to re-generate your API keys. You can achieve this by doing the following: Go to WooCommerce > Settings > Advanced > Rest API > Add Key > Permissions > Read/Write > Generate API key (don’t leave the description blank). Then copy both API Key and Secret to Printful > Settings > Stores > your Woocommerce store. Then go to Printful > Stores > View Store > Refresh data.
    In case this does not solve your issue, please make sure that the site URL in WordPress Admin > General settings matches the actual website URL. If the website is HTTPS, it should be HTTPS there as well.
    If all these steps do not provide a solution, please reach out to your web host for further investigation!
