UnityWebRequest on Android at an IPV6 address fails

Hello,

I'm trying to retrive some text form a hosted resource online. by doing that i want to use the hoster IPV6 as address. It works on editor but not on android (tested on android 6, 9 and 11)

I then did a generic test:

Code (CSharp):

1. IEnumerator Start()
2.     {
3.         string req = "http://[::ffff:801e:3464]/TR/PNG/iso_8859-1.txt";//  that is equivalent of: https://www.w3.org/TR/PNG/iso_8859-1.txt ,and works perfectly on editor
4.  
5.         var request = UnityWebRequest.Get(req);
6.  
7.        yield return request.SendWebRequest();
8.  
9.         if (request.result == UnityWebRequest.Result.ConnectionError ||
10.             request.result == UnityWebRequest.Result.ProtocolError)
11.         {
12.             GetComponent<TextMeshProUGUI>().text = "Error on getting file!\n\n" + request.error;
13.         }
14.         else
15.         {
16.             GetComponent<TextMeshProUGUI>().text = request.downloadHandler.text;
17.         }
18.     }

and it seems I cannot make a simple unitywebrequest on android, the answer is always "Cannot resolve destination host".

Where am I wrong?

 

you maybe need use https://

 

@LINYAN999 http or https in this case doesn't matter, same result

@Aurimas-Cernius thx for the answer, is there a workaround about it in the meantime? Or do you know when approximately will be fixed? IPV6 is becoming more and more a thing and our app works alot with the network
