Android Network Security Config doesn't works

I want to my application can access only to one sub-domain and do certificate pinning on connection to this url. I have setup Network Config since my minSDK 24.

Here is my Network Config:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config>
    <domain includeSubdomains="true">somebanking.com</domain>
    <pin-set>
        <pin digest="SHA-256">someWeOnkw7HXWyfGtCNfxcodeWGe96drme7CKNE=</pin>
        <!-- backup pin -->
        <pin digest="SHA-256"somexBsOVe1PQRwOsHsw3bsGT2VzIqz5K+codews=</pin>
    </pin-set>
</domain-config>

And in AndroidManifest under android:networkSecurityConfig="@xml/network_security_config"

When I changed my base url to different one, not even https. It's still working.
