We have lots of breweries using our WooCommerce integration, but occasionally we get similar messages from people struggling to set up the integration. So, here's the most common cause of problems and how to resolve it.

Whilst in theory there could be a number of causes for this error, from our experience, every time we have seen this before, the cause has been a misconfiguration in the web server config (typically Apache or Nginx) on your WooCommerce server. Essentially the Authorization header that we send over with HTTP requests gets stripped out before the request is passed to WooCommerce and so WooCommerce doesn't know how to respond.

A number of customers have reported that they resolved this issue by adding the following to their .htaccess file (assuming you use Apache as the web server, this is not applicable to Nginx).

Nginx (another common web server) will keep this header in by default, without you needing to add configuration to force it like with Apache.

If you manage your WooCommerce installation/server yourself, then hopefully that makes some sense, but if not it's would be worth getting in touch with the person/company who do and passing on this information.

Breww takes no responsibility for the correctness or suitability of the above code or other suggestions. Please make sure you're comfortable applying changes to your servers before doing so, which will be at your own risk.

Although this error is usually caused by the above, it's possible that it's being caused by one of the following reasons:
