UnityWebRequest freeze when use it on iOS + local network.
I'm running code that sends a simple GET request at regular intervals.
UnityWebRequest _request;
using (_request = UnityWebRequest.Get(targetUrl))
{
_request.timeout = TIMEOUT;
await _request.SendWebRequest();
if (_request.isNetworkError || _request.isHttpError)
{
Debug.Log("Scan Network Error");
}
else
{
Debug.Log("Scan Network Sucess : " + _request.downloadHandler.text);
}
}
I encountered the following issue.
Happens after launching the app for about 5 hours.
But maybe 0.1% UnityWebRequest freezes. There is no response, no timeout error.
After more than 5 min, I manually run _request.Abort() , UnityWebRequest returns a timeout error.
I encounter this issue about once a day.
After this error has occurred, If I send a similar GET request, there is no response and no error will be returned. I should re-boot my app.
My environment is below.
Unity 2019.2.6f1
iPad Pro 12.9 (third generation)
iOS 13.1
I think this freeze happens every 5 hours after launching the app.
It's nothing related to the number of requests.
