WWW-Class - Difference between 4.3.4f1 and 4.2.1f4? Couldn't connect to localhost

Unity Engine
1

Greetings!

I’ve some trouble with the newest Version of Unity that i can’t fix on my own.

Since i’ve switched to Unity 4.3.4f1 (from 4.2.1f4) i always get an error when i try to make a WWW GET/POST Request to my localhost server.

This is the error-Message of www.error: “502 Invalid argument”.

When i make a request to my live-Server everything is fine. And when i switch back to the older Unity version i’m able to make a working request to localhost, too.

So i guess there has something important changend. Any ideas how to fix that?

Here some code if it matters:

public WWW InternalPOST(Dictionary<string, string> Params, string Url)
    {
        WWWForm Form = new WWWForm();
        foreach (KeyValuePair<string, string> Param in Params)
            Form.AddField(Param.Key, Param.Value);

        WWW www = new WWW(Url, Form.data, SessionCookie);

        StartCoroutine(WaitForRequest(www));
        return www;
    }

private IEnumerator WaitForRequest(WWW www)

    {
        //yield return www;
        while (!www.isDone)
            yield return new WaitForFixedUpdate();

        //
        if (www.error == null)
        {
            Debug.Log("WWW Ok, Response:\n" + www.text);
            ParseResponse(www.text);
        }
        else
            Debug.Log("WWW Error:\n" + www.error);
    }

EDIT: SOLUTION FOUND: In Version 4.3.4f1 you have to remove the Proxy Settings (for Windows in the IE-LAN-Settings) because the option “Bypass Proxy Server for Local Addresses” is ignored. :roll_eyes:

Maybe due to this bug?

I was forced to switch back to 4.3.2…

I doubt that these are the same issues if yours is reproducable on any machine.

Mine seems to depent on the used network interface. While my main-pc has only one network interface where everything is still fine, the other has multiple diffrent interfaces.

Maybe a property at the www-Class to set a default network interface would help!?

At least it sounds promising if the Unity devs have a closer look at the recent changes on the www Class :slight_smile:

please create small repro project and bug report (and drop case number here).
