I build my app to iOS and all my requests and asset bundles work perfectly. I can do this over and over but when I leave the phone alone and come back in a few hours the app no longer works. I get (Filename: currently not available on il2cpp Line: -1) in the log.
-I am clearing the cache at start up in case that was the issue but it's not.
-Im not saving any bundles, paths, or content
-I have disabled strip engine code
As I said before everything works perfect no errors for a while and then just stops as if the app expires or something. I do have a paid developer account so that should not be an issue.
Documents and data stay at the same amount of memory no matter how many time I open and close the app so I don't see anything leaking there either.

Why do iOS web requests stop working after a few hours?

SSLHandshakeException during Web Request
I was working on the game and as per game requirements, I was fetching logos from the web server through Web Request. Here is my code:

yield return www;
if (www.error == null) {

long status = jsonObj [TAG_STATUS].i;
if (status == 1) {

List dataObj = jsonObj [TAG_DATA].list;
for (int i = 0; i < dataObj.Count; i++) {
Company companyItem = new Company ();

companyItem.CompanyId = companyObj [TAG_COMPANY_ID].i.ToString ();

Issue with sending Json via UnityWebRequest
Hello!
I want to send a simple JSON string to the Google Perspective API via UnityWebRequest. Everything seems to be working fine, but there seems to be a problem with my string. I always get an error saying *"Invalid JSON payload received. Unknown name \"{comment:{text:\"Test\"},requestedAttributes:{TOXICITY:{}}}\": Cannot bind query parameter. Field '{comment:{text:\"Test\"},requestedAttributes:{TOXICITY:{}}}' could not be found in request message."*. Here's my code:
IEnumerator MakeCall(){
string url = "https://commentanalyzer.googleapis.com/v1alpha1/comments:analyze?key=XXXXXXX";
string requestJson = "{comment:{text:\"Test\"},requestedAttributes:{TOXICITY:{}}}";
UnityWebRequest uwr = UnityWebRequest.Post(url, requestJson);
yield return uwr.SendWebRequest();
if (uwr.isNetworkError)
{
Debug.Log("Error While Sending: " + uwr.error);
}
else
{
Debug.Log("Received: " + uwr.downloadHandler.text);
}
}
When I try to send the same string via curl command in terminal, it seems fine and I get my answer from the API. Can anybody tell me where the problem could be?
Thanks!

How do I get into my StreamingAssets folder for the Web?
I'm working on a project where I need to access the StreamingAssets folder on a Webgl build. I've done it for mobile and PC. When it comes to web builds, I'm still learning the differences. I know that I need to perform a webrequest but I don't know how to find the url.

WebRequest 407 errors,Web Requests behind a proxy
Hi,
We are currently releasing our software to schools however they are unable to log in to our backend system in the app due to their proxy servers needing to authenticate our traffic. It seems it cannot be done using UnityWebRequest. All URLs used by the app are white listed at the school we are testing with. Exceptions are not a good option as most schools will be reluctant to add them.
We have tried using other methods such as HTTPWebRequest, adding DefaultCredentials to try authenticate yet we still get 407 errors.
Has anyone for any experience with doing Web Requests behind systems that require authentication?

Empty Error DownloadHandler
I am having a problem with a blank / empty error showing up in console. This error does not break the code (It keeps running after the error is displayed), and a try catch does not pickup the error.
var clip = DownloadHandlerAudioClip.GetContent(webRequest);
Above you can find the line of code which gets highlighted when I double click the error. I suppose it is something related to the DownloadHandler. Since I do not have a clear view on what is goign wrong and it doesn't have a negative effect on my program (Yet), it is rather annoying seeing this in my console.
Is this known? (Tried googling, did not give any clear results) I think its a bug in someway, should I report this?

HttpWebRequest doesn't work with Hololens
Hey guys, I'm trying to stream CCTV live video to Hololens, it works fine in Unity Editor but failed in Hololens with an exception of "connect failure TLS support not available".

Usage of DownloadHandlerAudioClip.streamAudio
Hi all,
I am trying to start playing an AudioClip before it has been completely download as hinted at in the documentation for [DownloadHandlerAudioClip.streamAudio][1]. I have written this sample code to illustrate the use I would expect to work:
private IEnumerator StartAudioStream()
{
// Prepare stream
string url = "www.brainybetty.com/FacebookFans/Feb112010/ChillingMusic.wav";
DownloadHandlerAudioClip downloadHandler = new DownloadHandlerAudioClip(string.Empty, AudioType.WAV);
downloadHandler.streamAudio = true;
UnityWebRequest request = new UnityWebRequest(url, "GET", downloadHandler, null);
// Start stream
UnityWebRequestAsyncOperation token = request.SendWebRequest();
AudioClip audioClip = null;
while (audioClip == null) // Ensure audio header completed
{
try
{
audioClip = DownloadHandlerAudioClip.GetContent(request);
}
catch (Exception) { }
Debug.LogFormat("Waiting for AudioClip: bytes={0}", request.downloadedBytes); // The complete file is 4834942 bytes
yield return 1f;
}
// Play AudioClip
source.clip = audioClip;
source.Play();

Establish a constant connection to a web server
I'm trying to create a connection between a unity game and an web server. Essentially there's 3 parts to the project I'm working on, the main game, a mobile app, and the web server. The Mobile app is able to send a request to the web server and update a value, which is stored in a database. I then need some way for the web server to tell the main game what has happened. Currently I'm having the main game send a web request to the server as well, and then reading the response, but I feel like there's a better way to go about this. Is there any way for the main game to send a single request to the web server, which will establish a connection where the server can respond whenever the mobile app has sent a request.

MultipartFormDataSection not working - Error: 403
This project goal is uploading user image to server so I am trying to test my api with ***UnityWebRequest*** and ***MultipartFormDataSection***.
And I found out I am not able to pass values with ***MultipartFormDataSection*** but ***WWWForm*** is successful to pass values.
**This is my Multipart Code:** List formData = new List ();
formData.Add (new MultipartFormDataSection ("fileName", "i_am_fileName.png"));
formData.Add (new MultipartFormDataSection ("fileName2", "i_am_fileName.png2"));
UnityWebRequest wwwGetURL = UnityWebRequest.Post ("http://www.{myserver}.com/projects/BoLe/api/saveimage.php", formData);
