 *  Fix: Read the response even if writing the request fails. This means you'll get a proper HTTP
    response even if the server rejects your request body.
 *  Fix: Use literal IP addresses directly rather than passing them to `DnsOverHttps`.
 *  Fix: Embed Proguard rules to prevent warnings from tools like DexGuard and R8. These warnings
