 * [@lenbook](https://wordpress.org/support/users/lenbook/), That’s probably because
   the host might be blocking some port or the Smush API.
 * You mind checking with the hosting service, if they can possibly look into the
   issue and do something about it?
 * This error occurs when Smush is unable to lookup the API servers, so it’s mostly
   related to the hosting.
 * Cheers

 * the hoster asking for WP Smush port. Can you please provide this info?

 * [@lenbook](https://wordpress.org/support/users/lenbook/), Smush uses the default
   WordPress HTTP API to post to API servers.
 * So, you need to checkout with host if that is being blocked.
