title: How to make the Google Cloud Platform App EngineStandard access non-secure endpoint
body: <p>From the front-end app that built from App Engine Standard, we have a print request send to <a href="http://70.53.4.12:9100" rel="nofollow noreferrer">http://70.53.4.12:9100</a> which is a raw printer port and it works on the locally development box and just not working in the Cloud, it compliant about the endpoint is non-secure, how can we bypass this and let Cloud accept this endpoint as HTTP only like an exception.</p>
  
  <p>Here is the error message showing in console.</p>
  
  <p>VM9:1 Mixed Content: The page at '<a href="https://my-dev.domain.com/" rel="nofollow noreferrer">https://my-dev.domain.com/</a>' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint '<a href="http://70.53.4.12:9100/" rel="nofollow noreferrer">http://70.53.4.12:9100/</a>'. This request has been blocked; the content must be served over HTTPS.(anonymous)</p>
  
  <p>The IP 70.53.4.12 is public accessible, so I can send print request from my home to the printer sitting in my office through port forwarding, but can't do it from the Google Cloud Platform App Engine.</p>
  
  <p>Thanks in advance!</p>
