    I’m seeing cURL 28 and Missing Header/body separator errors on a host with no firewall and no security plugins. I tried disabling all plugins and got the same result. Tried a different version of the plugin (3.2.3) and got the same result. It’s either a cURL 28 error or:

    “Missing header/body separator
    There was an error connecting to the image compression server. This could mean either the server is temporarily unavailable or there are connectivity issues with your internet connection. Please try later.”

    The logs all have the same thing in common:

    Cannot establish connection with reSmush.it webservice. Please try later

  • @yobofofas The curl 28 error usually occurs if your website is blocking the request to third party API, please check with your host if your website is behind firewall, if yes please temporary disable the firewall and check if the image compression works?

    Hey Harshad,
    I can 100% confirm my host is not using a firewall and there is nothing on the website that is blocking the AP!. I sent you logs showing that there was no response?from the smushit server.

    I can confirm this because I work as a Sales Engineer for Flywheel, the company that hosts this site. I can walk you thru the entire tech stack of our server setup if you like. There is no firewall or plugin blocking the API. I have tried disabling all plugins except for WP Optimize and still, there was no connection to the smushit?server. Please look at the logs I sent.

    @yobofofas Our development team is looking into the issue.

    Once the issue is fixed, we will update you on the same.

    Thank you for your time and patience.
