Why the link can't be blocked?

Do you have access to support, or are you a home user?   You may have found a bug that Support needs to investigate.

I have reproduced your symptoms.

I think I repeated your problem because I repeated your mistake.

Escape all of the "/" characters -- replace them with "\/" -- and see if it fixes the problem.   I do not have time to repeat my tests right now.

Sharp eye, Doug!  I admit to scanning too often without looking closely.

Perry, if you're not using decrypt and scan for HTTPS traffic, you won't be able to block traffic inside the encrypted tunnel, just as Doug commented twice above.

Yes, Perry, if you don't install the Proxy CA in all computers, they will get a certificate warning.

Hi,

Perry the error you get looks like it is from the firefox.

The firefox uses by default not the certifcate store from windows.

Here you have to import the CA in the firefox itself.

Hi DKKDG,

I am using Google Chrome and the certificate imports by double click at window file manager.

You need to use GPO to push the certificate to all clients.   It is needed whether you https inspection or not, but it is more critical with https inspection enabled.

You are running into common startup problems, so you need to do some research.  I have tried to use this forum to document everything that I figured out as I worked with web filtering, because the manuals do not provide any tutorials.   

My earliest material is in the WiKi section, and generally foundational.  There is a post about the UTM Architecture, which contains undocumented information that I learned by unhappy surprise, a tutorial about how the different pieces of the web filtering configuration work together, and a discussion about the different security mechanisms and how they fit together. 

The newer material is pinned at the top of the Web Filtering sub-forum.    The most recent entry is "Troubleshooting Web Filtering", which you may find useful for rapid response to the next problem.   "Web Filtering Lessons Learned" is the longest document.   It includes a sample proxy script, an explanation of why I use both Standard Mode and Transparent Mode together, and related matters.

Hi DouglasFoster,

First of all, thanks your help and teaching.

I already installed the CA by GPO and checked by CertMgr but the problem still coming.  Otherwise , I will not call help again. (T_T)

Does it not work related to the Cloudflare setting?

Everyday, I am trying and error, I feel very tired!

YEAH! The warning hasn't prompt again!
