Internet connection blocked for Steam (Error 105) and Riot Games after installing KTS

[samettaksim]

Hello,

I recently purchased and installed Kaspersky Total Security on my Windows laptop. However, immediately after installation, I am unable to connect to Steam (Error Code: 105) and Riot Games (Riot Client / TFT).

While Google Chrome works perfectly fine, these gaming applications report "No Internet Connection." I have already tried the following steps but none of them worked:

1. Enabled Game Mode and Do Not Disturb Mode.

2. Added Steam and Riot Games to the Exclusions list and marked them as Trusted Applications.

3. In Trusted Application settings, I checked "Do not scan encrypted network traffic."

4. Disabled "Encrypted connections scanning" under Network Settings.

5. Disabled "Inject script into web traffic" under Traffic Processing.

6. Performed a full Network Reset in Windows.

7. Completely uninstalled Kaspersky (internet worked perfectly after uninstalling) and reinstalled it (internet blocked again).

System Details:

• OS: Windows 10/11

• Product: Kaspersky Total Security

• Network: Wi-fi

• Error: Steam Error 105 / Riot Client Connection Error

Is there a specific NDIS filter or network driver setting that blocks these gaming ports on restricted networks like dormitories? How can I fix this without completely disabling the protection I paid for?

Thanks in advance.
