Squid ssl filter CA issues certificates for ip, not domain

I put two photos first

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

There's nothing that activates. When you try browsing https://8.42.96.25 (or any other IPs that www.roblox.com resolves to) instead of https://www.roblox.com, you get exactly the same result without any proxy. Because the site clearly does not have any of it's IPs in its certificate's SAN.

Thanks for your good guidance
But what is this problem?

Why does SSL filtering enable HTTPS / SSL interception when it is enabled? In squid

Is it possible to connect some Android apps to mobile phones?

:D :D

I know my questions are a lot.
But I did not find a place.

Thanks for the time you left

Well I don't get the question really… that's the whole purpose of the feature. If you don't want it, do NOT make the proxy transparent (or whitelist stuff that's not supposed to get proxied).

Again thanks for the guidance

But to control some sites, I need to enable this option, and on the other hand, I have the problem
