IOs error network

Hi to all

I published my app on PlayStore and everythings works, but after i generate the app for IOs the networks didn’t work.

API not working. If I try to GET or to POST data to server not working.

I make some search but nothing works.

I add these keys to Info.plist, but nothing change!

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>domain.com</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Include to allow HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Include to specify minimum TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
