UnityWebRequest error 0 in Editor, but not in WebGL build

I’m trying to send a UnityWebRequest to a server.
It works perfectly on the WebGL Player, but not in the Editor

private static IEnumerator SendWebRequest(UnityWebRequest webRequest, UnityAction doneAction)
    {
        using (webRequest)
        {
            yield return webRequest.Send();    
            if (webRequest.isError)
            {
                throw new Exception("Could not connect to backend: " + webRequest.responseCode);
            }    
            doneAction();
        }
    }

In Editor, I simply dont receive anything from the server. The responseCode is 0.

CORS has been set up accourdingly to the Unity Manual.

I can get a response to other servers, e.g. www.google.com, it’s just my server that is not working. Is there something else that needs to be configured in order for it to work?

I am having the same problem :frowning:

Hey guys! My problem was that the server did not have a valid certificate and unity was just discarding the entire packet. In the built version it worked with some warnings. IMO this should be improved to give a proper error message stating that the certificate is invalid, just like in the build.
