http: Report errors reading discs

[unknownbrackets]

This also implements better error handling and some cleanup:

• All FileLoaders that use a backend_ now are ProxiedFileLoaders. This cuts down on duplicated code.
• We no longer wait indefinitely for an HTTP response when reading remote discs, and instead timeout.
• Errors loading games from remote discs are now reported more clearly, instead of always "error reading file".

That really looks like there's a firewall blocking it, but maybe something is just making the connections really slow...

I have a firewall on my phone but I tried disabling it and I also allowed ppsspp in the windows firewall(I have only the windows firewall and the windows defender)but nothing changes

As I said,I dont have any problems transfering files(fast)over wifi(making an ftp server on my phone and accessing it from my pc)

[unknownbrackets]

The reason I suspect a firewall is that a typical behavior for firewalls is to accept connections on a port (e.g. 49845), but then ignore any data sent and never respond with any data. That matches the before and after pretty much exactly.

If you navigate to this URL on your phone, does it start downloading cube.iso? http://192.168.1.11:49845/cube.iso

The connection that is failing is the one from your phone (source) to your PC (destination.) So that would mean a PC firewall (or network device the PC is connected behind) would be getting in the way.

If the download of cube.iso works fine (and fast) from your phone in Chrome, it probably means that some antivirus software or hardware is intercepting the request and stripping the range request, or something. I haven't seen this behavior before, but many routers do have protocol-aware protections.

Oops, I think I must've pressed something wrong in vi, there's a typo, fixed in 809c0f3.

When I try to download it(on my pc and phone),I get
"This server only supports range requests."

With this typo fixes,I am back to black screen and nothing happening and the debugger now just says that he found a game at that IP and that's all

And also if I try to share my games on my phone,on my pc ppsspp is scanning endlessly but I can access the list on my pc with firefox but if I try to download something,I get the same error
"This server only supports range requests."

[unknownbrackets]

Oh sorry, yes. It will say that. But it means you're getting through the firewall.

So it stays at a black screen without any timeout or error after 60 full seconds? Hm.

Yes,almost like ppsspp freezes...one time my phone was barely reacting to anything and the os ask me if I want to kill the process
I have 3 games on my phone and they all work fine but if I try them like this(streaming from the pc)ppsspp freezes
