App Transport Security policy requires the use of a secure connection - IOS 9

Question

I'm facing problem connection to API with using IP address. Even I had add the following code to plist, it still show error as below:

"http://xx3.xx.xx8.xx7/xxx/xxx/ error: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection."

This is the code I add to the plist

     <key>xx3.xx.xx8.xx7</key>
        <dict>
            <key>NSThirdPartyExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
            <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
            <false/>
            <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
    </key>

Document Allowing Insecure Connection to a Single Server here. So you must add NSAppTransportSecurity to your info.plist file in truth way like flowing (to show Info.plist in source, in Xcode right click to Info.plist "Open As"->"Source Code")

To configure a per-domain exception:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <!--others key-->
    <key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>
            <key>insecure-domain1.example.com</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <key>NSExceptionRequiresForwardSecrecy</key>
                <false/>
                <key>NSExceptionMinimumTLSVersion</key>
                <string>TLSv1.0</string>
            </dict>
            <key>insecure-domain2.example.com</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <key>NSExceptionRequiresForwardSecrecy</key>
                <false/>
                <key>NSExceptionMinimumTLSVersion</key>
                <string>TLSv1.0</string>
            </dict>
        </dict>
    </dict>
    <!--others key-->
</dict>
</plist>

after edit Infor.plist file look like following:

Or disable ATS:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    ...
    <key>NSAppTransportSecurity</key>
    <dict>
        <!--Include to allow all connections (DANGER)-->
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>
</dict>
</plist>

after edit Infor.plist file look like following:
