Can’t connect my website to the extension “Please add and enable domain”

ello

I tried to connect my website to the extension with authentification and secret key but it is still no working. I deactivated wordfence, cleared the cache, deactivated cloudflare security, uninstalled and reinstalled the plugin/extension, added code to htaccess.
I still have this error message when I try to make orders : “Please add and enable domain www.****.com to fulfil your AliExpress order.”

When I use the secret key I can import products and sync tracking numbers. But I cannot fulfil orders automatically.

I don’t have any idea how to fix this issue now.

Can you help me?

Thank you
