title: 401 Error on rest apis on default woocommerce API requests
body: <p>Their is a strange 401 error comes in basic rest APIs.
  For example:</p>
  <blockquote>
  <p><a href="https://parosi.techchef.org/wp-json/wc/v3/products/categories?consumer_key=ck_f76c28eae983eb9b237d6bb81dd5b6c1ee35d16f" rel="nofollow noreferrer">https://parosi.techchef.org/wp-json/wc/v3/products/categories?consumer_key=ck_f76c28eae983eb9b237d6bb81dd5b6c1ee35d16f</a></p>
  </blockquote>
  <p>I have already checked and trouble shoot following steps.</p>
  <pre><code>1- Enable the legacy REST API is checked
  2- I have made new rest api and applied the same consumer key
  3- I created new admin and tried
  4- I replace htaccess with default wordpress
  5- I have upgrade both wordpress and woocommerce version to latest
  6- I have disabled all other plugins
  </code></pre>
  <p>But none of the things work still, rest every thing is working fine but rest-API authentication for woocommerce does not</p>
