Failed to load resource: net::ERR_INSECURE_RESPONSE

IS there a way to trick the server so I don't get this error:

Content was blocked because it was not signed by a valid security certificate.

I'm pulling an iframe of an html website into another website but I keep getting the console (chrome) error in the title of this question and in internet explorer it says:

Content was blocked because it was not signed by a valid security certificate.


Solution 1:

Your resource probably use a self-signed SSL certificate over HTTPS protocol. Chromium, so Google Chrome block by default this kind of resource considered unsecure.

You can bypass this this way :

  • Assuming your frame's URL is https://www.domain.com, open a new tab in chrome and go to https://www.domain.com.
  • Chrome will ask you to accept the SSL certificate. Accept it.
  • Then, if you reload your page with your frame, you could see that now it works

The problem as you can guess, is that each visitor of your website has to do this task to access your frame.

You can notice that chrome will block your URL for each navigation session, while chrome can memorise for ever that you trust this domain.

If your frame can be accessed by HTTP rather than HTTPS, I suggest you to use it, so this problem will be solved.

Solution 2:

Sometimes Google Chrome throws this error, even if it should not. I experienced it when Chrome had a new version, and it needed to be restarted. After restarting the same page worked without any errors. The error in the console was:

net::ERR_INSECURE_RESPONSE

Solution 3:

I still experienced the problem described above on an Asus T100 Windows 10 test device for both (up to date) Edge and Chrome browser.

Solution was in the date/time settings of the device; somehow the date was not set correctly (date in the past). Restoring this by setting the correct date (and restarting the browsers) solved the issue for me. I hope I save someone a headache debugging this problem.
