We’ve been having the same problem in the last few weeks on 3 different Woocommerce websites we have.

I followed the advice given here and added code snippets:

It seems to have done the job nicely, though I think the code snippet *may* interfere with the new WC checkout block, as ‘humans’ were unable to place orders as the Place Order button seemed to stop working on the one site we had that used the new checkout experience, or it may have been a separate unrelated issue which I haven’t been able to resolve yet, but after reverting to the ‘classic’ checkout block the site works fine and humans can now place orders successfully.

According to the plugin documentation, this error occurs when access to xmlrpc.php is blocked. Which many webhosts are doing now due to security concerns, as this method of communicating with a WordPress site is now considered ‘outdated’ and vulnerable to external attack.

I think you need to disable Adblock, I had the same problem too.
