Squid ssl filter CA issues certificates for ip, not domain

[jzzmatt]

I have the same problem too, my self sign cert is not recognize , i don´t use transparent proxy
for site blocked on my squidGuard, which are https, i receive an erro like " your connection are not private"!!

[gersonofstone]

My recomendation is create new certificatte for squid

I tried creating a new CA, but it didn't work.

[gersonofstone]

What is the issue or error?

Add a printscreen

The issue is described in my original post.

Hello friends
I've enabled Transparent Proxy and SSL Man In the Middle Filtering on pfsense.
My pfsesne version is 2.3.4-RELEASE-p1 (amd64).
I've implemented the following rules for HTTPS SSL.
SSL / MITM Mode: Splice Whitelist , Bump Otherwise
SSL Intercept (s): LAN
SSL Proxy Compatibility Mode: Modern
DHParams Key Size: 2048
CA: Self-Signed

I use SSL Filtering in Squid and I created a certificate in pfsense and I can login to Https through Domain Name.

• Tip: I have installed my certificate on the system.

For example, the site (https://www.roblox.com) looks like the following

But when I log in through the IP of the same site, I get an error certificate like the one below

Second Photo

In Android apps on the mobile phone, all connections are through the IP, and if I connect to the Internet via WIFI, that the Pfsense firewall is on the route, none of the programs will connect (such as a telegram)

Friends and Teachers Please advise how to resolve this issue.

You cannot use any such thing, WTF. You need your own CA that's able to issue certificates on the fly for Squid.

I put two photos first, through the domain name of a site, I entered the site and the second image through the IP I entered that site. I entered the site successfully in the first photo, but in the second photo there is a certificate error.
Also, in Android applications, such as the telegram, it uses the IP to connect to the server, and it does not provide a connection error.

No idea where did you put two photos.

I am sorry I did not understand
Probably a problem with my upload center, which is not a photo.

I'm uploading again

I am able to log in to HTTPS sites if I enter the domain name successfully with the internal certificate, but if I get the IP address of that site, I get an error certificate?
Why this error occurs?

This problem is problematic on Android phones to enter programs such as telegrams that use HTTPS and IP, and the program does not work?
Is there a way to set up an IP certificate?
Because it seems that the internal certificate we create works properly with the domain name of the sites.
Thank you friends

This is an expected and documented behaviour, and not any issue with Squid. You would get exactly the same "problem" without Squid.

So why when the HTTPS / SSL Interception option enables SSL filtering.

This activates this and does not exist when it is disabled?
And my Android phone that connects to this firewall via Wi-Fi

If this option is enabled, some of the programs will not connect to the Internet? But if this option is disabled, they will be connected.

I even installed the internal certificate I built on my mobile phone, but the problem remains
