 * Hi,
    after updating to wordpress 5.6 and doing a site diagnose I am getting a
   loop back request error which (after testing all my plugins) orginaties from 
   the wppizza plugin, or at least it only shows up with wppiza active. This is 
   the error
 * `cURL error 28: Operation timed out after 10000 milliseconds with 0 bytes received(
   http_request_failed)
 * What could cause such an error and how do I prevent wppizza from triggering it?
 * Is there a setting I can turn of or is this a bug?
 * Thanks and greetings

 * wppizza doesnt use curl requests anywhere (though some wppizza premium extensions/
   plugins do)
 * in any event, curl errors are caused by curl setup and/or server related curl
   issues and/or things (other plugins perhaps, but that’s unlikely) that block 
   curl requests or a number of other possible causes
 * you should search for “cURL error 28” or similar – or indeed talk to your server
   administrator / host – as this is nothing the plugin has any control over I’m
   afraid
 * here’s a starting point

 * on second thoughts, let me check something here for a bit
    in any event though,
   even if it is related to what i think it might be , if it only happens in the
   site health check and nowhere else, you can safely ignore this for now unless
   you see some ill effects elsewhere
 * will get back to you here when i’ve messed around with a few things to check 
   stuff

 * ok, so it seems wp changed something in 5.6 (might have been 5.5, but not sure
   and it’s not relevant and I’ll spare you the details)
 * the next version of the wppizza plugin will address that, but for the moment,
   you can ignore this as it’s a false positive somewhat and most certainly not 
   critical (with regards to the wppizza plugin)
 * thanks for letting me know though
