1) The permalinks are set on Plain

2) There is no valid SSL certificate problem installed. You might see an error like: cURL Error: SSL certificate problem: unable to get local issuer certificate.

3) The logs show: Response body has invalid JSON.

1) Go in your WordPress dashboard to Settings > Permalinks and configure your permalinks to anything but Plain. Try again to authorize.

2) Activate and install a SSL certificate via your hosting provider and try again.

3) This can have 2 different solutions. It is either related to the permalinks setting also or access to the WooCommerce REST API is blocked by a firewall, server or hosting provider.
3.1) Go in your WordPress dashboard to Settings > Permalinks and configure your permalinks to anything but Plain. Try again to authorize.
3.2) Check with your hosting provider what is blocking the WooCommerce REST API and make sure it will get unblocked. Try again to authorize, once this is done.

1) Corrupt .htaccess file

2) The server firewall blocks any requests from the Woosa midlayer server

1) There can be many reasons why a .htaccess file is corrupted. It can happen already by installing a new plugin for example. Luckily it’s easy to solve!

Log in to the root folder of your WordPress installation via FTP and rename the .htaccess file to .htaccess_old. Next go to your WordPress dashboard > General > Permalinks and hit the save button. This generated a new and clean .htaccess file. You can check this by going to your WordPress installation root folder via FTP again.

After that, try to click the button Click to register again.

2) To solve this issue we advise to whitelist the Woosa midlayer IP addresses on server level. You can find the IP addresses below:

We use ports 80 and 443.
