net::ERR_INSECURE_RESPONSE in Chrome : <p>I am getting an error net::ERR_INSECURE_RESPONSE in the Chrome console when fetching some data from my API</p>

<p>This error usually occurs as a result of an unsigned certificate; however, it is not an issue with this because I have a valid and signed certificate. </p>

<p>The error doesn't happen often at all and it goes away if I restart my Chrome browser. It also doesn't occur in any other browser at all (tested on Safari, Mozilla, Opera)</p>

<p>Any idea why this is happening? Is this just a browser bug?</p>
