I've scoured the web (and here) but still can't find detailed information on how to properly debug a website in which Chrome reports is insecure.
- no http/https errors in the browser console
- used dev tools to find
- http: function to prove not exists cleared browser cache tried
- incognito mode other browsers report secure
Everything I've read about this exact scenario eventually fixes itself with time. This is not professional to just wait.
I'm simply looking for a way to see exactly what Chrome thinks is insecure so I can fix it. Is this even possible?
I finally found the answer. There is an initially hidden "Security" tab in dev tools that lists all errors Chrome sees.
All I had to do was click the 3 vertical dots in the upper right corner of dev tools and choose "More Tools" submenu and then "Security".
