Try this first:

1. Upgrade the Datafeedr plugin to the newest version (if you are able to).
2. Go here: WordPress Admin Area > Tools > Datafeedr > Debug.
3. Scroll to the bottom of the page.
4. Under "Factory host", replace "factory3.datafeedr.com" with "75.101.166.188" (without the double quotes) then click [Save].
5. Then click the [Update Products and Settings] button.

Now your store should successfully update.

Still not working?

If you still receive this error after following the steps above, it's probably because your web host is blocking our domain name and IP address. Ask your web host why it's blocking the connection to "factory3.datafeedr.com" and "75.101.166.188" and to unblock us.
