Both UnityWebRequest and WWW are not able to download any file from LAN

[nina32176]

Hello,
I have a project where I want to download XML file.
I know there are many ways to do this, I tried both UnityWebRequest and WWW .
Both methods works with URL like:
“OLS Tutorial”
but are unable to download:
“http://192.168.0.118/update/data.xml”;
I get “request timeout” on both PC in Unity Editor and on Android phone.

What is even more crazy, is that when I copy the mentioned LAN URL, the one with 192.168.0.118, to web browser, on both PC and Android phone I get that XML file open correctly.

So that rules out wrong LAN/wrong IP/http server not running/firewall.

What is wrong?

Networking, UnityWebRequest, WWW, Postman, curl, WebAPI, etc:

Using Unity for subscription lists

As with all network code, get it working with Postman or curl first. That makes it NOT a Unity problem. Solve the networking first. You must solve that or anything else is irrelevant. Once you have that working, then try and port it to UnityWebRequest. If it still doesn't work, one handy debug solution is to hook up a proxy like Charles and compare the functioning output from Postman / curl to the output from Unity, and from that reason about where your issues are.

Unity web request acting stupid.

Always get network stuff working outside of Unity in either curl or PostMan, then connect a proxy such as Charles and start trying to replicate the traffic shape with UnityWebRequest. Any other way risks wasting a lot of your time for trivial issues that only the above way will instantly reveal.

And setting up a proxy can be very helpful too, in order to compare traffic:

“http://192.168.0.118/update/data.xml”;

Is that really an HTTP server that you host, or is it a shared folder?
If it’s the later, please use file:// or smb:// protocol for it (IIRC file will only work on Windows).
Try smb://192.168.0.118/update/data.xml
If you try file, you need 5 (five) slashes after file:
