Ubuntu 14.04 - Apache - Site not fully secured


Hi Guys,

I was able to install Let’s Encrypt on my Ubuntu 14.04 with Apache Web Server but when I checked the site, it servers https but doesn’t have the lock icon. It says “not fully secure”. You may check this link: https://www.kollabnorth.com/

My Server is a Compute Engine on Google Cloud Platform.


You seem to have a redirect loop on your site right now, but the “not fully secure” issue can be explained by something called “mixed content”.

You can read about it here:


Thanks _az,

Can you also provide me a link of an updated installation process of Let’s Encrypt on Ubuntu 14.04?



Hi _az,

I configured something, the site is now accessible but it doesn’t have the green lock/not fully secured. Can you help me figure out this one?



I checked again on the “whynopadlock.com” and below is the result:

A file with an insecure url of “http://www.w3.org/Icons/valid-xhtml10” was loaded on line: 373 of https://www.kollabnorth.com/.


Hi _az,

This is ok now, was able to resolve this with the help of https://www.whynopadlock.com/. I edited the line 373, made it https.



Use FireFox or Chrome (Desktop), then CTRL + Shift + I, then click the “Console” - tab.

There are the files which are loaded via http instead of https.
