I’ve been trying to create Wordpress API credential to post on my new blog. I am on free plan on Wordpress. But it couldn’t connect and the error message is “Couldn’t connect with these settings. Not Found”.
I decided to purchase a domain and buy a hosting service. At first I ran into the same problem described above. But then site health check recommended upgrading PHP version. After upgrading PHP to the newest version, I could finally create wordpress credential.
