UnityWebRequest not working on Android API level 33

[JesusMartinPeregrina]

Hello!
Im trying to get the daytime from internet.

I have tried it with an UnityWebRequest to"https://worldtimeapi.org/api/ip" and then parsing the json received.
I have tried it with a WebRequest to “https://www.google.com” and then parsing the time from response.Headers[“date”].

Both methods works on editor but not on Android.
As suggested in some forums I have checked Custom Main Manifest in Publishing settings and edited it adding android:usesCleartextTraffic=“true”> but it doesnt work, the error says “cannot resolve destination host”.

My AndroidManifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.unity3d.player"
          xmlns:tools="http://schemas.android.com/tools"
          android:installLocation="preferExternal">
  <application android:theme="@style/UnityThemeSelector"
               android:icon="@mipmap/app_icon"
               android:label="@string/app_name"
               android:usesCleartextTraffic="true">
    <activity android:name="com.unity3d.player.UnityPlayerActivity"
              android:label="@string/app_name">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
      <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
    </activity>
  </application>
  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
</manifest>

I have tried to implement a CertificateHandler as mentioned here

but it doesnt work either.

Could anybody help me please?

Unity 2021.3.14f1
Minimum API Level 33
Im using Google Movile Ads and Google Play Games, so there are more that one manifest file in the project but I guess Unity auto merge them on the build process isnt it?

Networking, UnityWebRequest, WWW, Postman, curl, WebAPI, etc:

Using Unity for subscription lists

As with all network code, get it working with Postman or curl first. That makes it NOT a Unity problem. Solve the networking first. You must solve that or anything else is irrelevant. Once you have that working, then try and port it to UnityWebRequest. If it still doesn't work, one handy debug solution is to hook up a proxy like Charles and compare the functioning output from Postman / curl to the output from Unity, and from that reason about where your issues are.

Unity web request acting stupid.

Always get network stuff working outside of Unity in either curl or PostMan, then connect a proxy such as Charles and start trying to replicate the traffic shape with UnityWebRequest. Any other way risks wasting a lot of your time for trivial issues that only the above way will instantly reveal.

And setting up a proxy can be very helpful too, in order to compare traffic:

Thanks for the answer Kurt, I finally found the problem… it was the most stupid thing you can imagine…
I just brought a phone from my job to home for finishing a task and I forgot to connect it to my house wifi… hahaha shame on me.
Now Im looking how to remove this thread from the forum.
