title: Stuck with woocommerce_rest_authentication_error: Invalid signature - provided signature does not match
body: <p>Below issue was posted by me on <a href="https://github.com/XiaoFaye/WooCommerce.NET/issues/414" rel="nofollow noreferrer">https://github.com/XiaoFaye/WooCommerce.NET/issues/414</a> but since this may not be related at all to WooCommerce.Net but on a lowerlevel to Apache/Word/WooCommerc itself I am posting the same question here</p>
  
  <p>I am really stuck with the famous error:</p>
  
  <p>WebException: {"code":"woocommerce_rest_authentication_error","message":"Invalid signature - provided signature does not match.","data":{"status":401}}</p>
  
  <p>FYI:</p>
  
  <ul>
  <li>I have two wordpress instance running. One on my local machine and one on a remote server. The remote server is, as my local machine, in our company's LAN</li>
  <li><p>I am running WAMP on both machines to run Apache and host Wordpress on port 80</p></li>
  <li><p>The error ONLY occurs when trying to call the Rest api on the remote server. Connecting to the local rest api, the Rest Api/WooCommerceNet is working like a charm :-)</p></li>
  <li>From my local browser I can login to the remote WooCommerce instance without any problem</li>
  <li><p>On the remote server I have defined WP_SITEURL as '<a href="http://[ip" rel="nofollow noreferrer">http://[ip</a> address]/webshop/ and WP_HOME as '<a href="http://[ip" rel="nofollow noreferrer">http://[ip</a> address]/webshopin wp-config.php</p></li>
  <li><p>Calling the api url (<a href="http://[ip" rel="nofollow noreferrer">http://[ip</a> address]/webshop/wp-json/wc/v3/) from my local browser works OK. I get the normal JSON response</p></li>
  <li>Authentication is done through the WooCommerce.Net wrapper which only requires a consumer key, consumer secret and the api url. I am sure I am using the right consumer key and secret and the proper api url <a href="http://[ip" rel="nofollow noreferrer">http://[ip</a> address]/webshop/wp-json/wc/v3/ (see previous bullet)</li>
  <li>I already played around with the authorizedHeader variable (true/false) when instantiating a WooCommerce RestApi but this has no effect</li>
  </ul>
  
  <p>Is there anybody that can point me into the direction of a solution?</p>
  
  <p>Your help will be much appreciated!</p>
