Unable to get WU unless connected via VPN

Post by Loohi »

Hey guys,

It's been a couple of days now, since I am unable to get my GPU assignment, unless connected via VPN.
I woke up one morning, and my GPU was idling, unable to get the next assignment. I seriously cannot think of anything that would have changed on my machine between when it was perfectly working, and now.

here is the log below, together with more information.
Please note that I have rebooted my machine multiple times, as well as my router, and reinstalled FAH a number of times. The issue occurs even when windows firewall is turned off.

When I connect via a VPN, it's no problem, my assignment downloads just fine and I can start folding. Thanks for your help if you have any idea :)

EDIT 1: To substantiate the headache: I just reinstalled FAH using express settings, and my GPU is not recognized. However, when reconnecting via VPN, the GPU gets recognized just fine.

Code: Select all

Re: Unable to get WU unless connected via VPN

Post by bruce »

There are probably two different questions. Based on the log you posted, HTTP_BAD_REQUEST is a strange error but it should be easy to answer. Are you able to open http://171.67.108.45 and/or http://171.64.65.35 with or without your VPN? When communications with the Assignment Servers is blocked, you won't be able to get an assignment. You'll have to figure out what is disrupting or blocking that connection.

The other issue is why the GPU was/was_not recognized earlier. Since that appears to no longer be an issue, we can ignore it or you can provide more information so we can investigate it. There will be information in one or more of your earlier logs which can be found in %APPDATA%\fahclient\logs. (It's likely that it's just be another aspect of problem #1.)

I can access both http://171.67.108.45 and/or http://171.64.65.35 with or without VPN

here is the initial log, when my GPU was not recognized

Where are you from ? Are you behind a corporate or institutional network ? Do you have some security tools installed on the machine ?

Thanks for your help.

I am in Singapore, this is a home network, running basic Windows 10 Defender/Firewall (tried disabling them and didn't help)

The puzzling things are:
- my network configuration has not changed between the time it worked and the time it stopped working
- I restored my system using a barebone system image from weeks ago (fresh after reformat, when FAH was working wihtout troubles), and it did not work.

My best guess (and I don't like it), is that my ISP has suddenly blocked something, maybe a port? Which would explain why the connection work behind VPN?

It could be your ISP, or a router change, but basically the FAHClient process needs the same permissions to download and upload data as a browser such as Firefox, Internet Explorer or Chrome. Firewall software, either running on your systems or your ISP's, can block the client if it is not included on the "permitted" list. That you can access the web sites using a browser, but FAHClient can not, does point to that kind of security or configuration issue.

I see, as indicated above, I am able to access http://171.67.108.45 and/or http://171.64.65.35 without any trouble with Chrome, but for some reason the FAH client cannot.

I do not believe it is a firewall/security issue, otherwise FAH client would also not work behind VPN, correct?

Your ISP might have changed something, .... or Windows 10 might have changed something internally.

FAH uses port 8080 or port 80. (Port 80 is the default port for a browser looking for a http:// connection.)

FAH is designed to work with port 80, which is the default for http:// (In other words FAHClient is just like instating another browser on your system -- as Joe_H just said (That's as far as the connection and protocol is concerned, although firewalls don't find FAH on their "white list" of approved programs, if your software configures the firewall based on that information.

I think I ruled out Windows changing something by reverting back to an old (working state) version of windows 10 (post reformat) from a couple weeks ago, back when FAH was working fine.
I also checked the timing, and there was no windows Update that happened in the lapse of time where it stopped working.

My money is on the ISP, which sucks because I don't really know where to start for this.

Apologies for 3 successive posts, but I tried running FAH on my android phone and was able to do so, while connected to the same router as my pc. So I'm now not sure whether my isp is responsible at all.. Unless the phone client uses different servers?

Re: Unable to get WU unless connected via VPN

Post by bruce »

Two things are required for a fresh install to recognize a GPU initially.
1) The driver installation must include OpenCL which is normally packaged with drivers from NVidia (or ATI) and often not included by Microsoft. [See elsewhere for the continuing controversy about MS drivers with Windows10]
2) GPUs which were supported at the time the current version of FAHClient was released are recognized instantly. For GPUs that didn't exist at that time, FAH connects to the internet and downloads an updated version of "GPUS.txt." It takes some time for that update to be received. Support soon becomes available, but you'll have to wait a few minutes before manually adding a slot for your GPU.

*** The message "Exception: Option 'gpu-index' has no default and is not set." is NOT helpful, but what it really means is contained in an earlier statement:
...
10:43:50: OS Arch: AMD64
10:43:50: GPUs: 0
10:43:50: CUDA: 5.2
...
which could be summed up: You can't add a GPU when no supported GPUs have been recognized ... (yet).

[I expect that when the next version of FAHClient is released, all current GPUs will again be recognized but as new ones come out, it'll still need to download the updates in GPUs.txt.]

The Android client is almost entirely separate from the regular folding clients. It is programmed and supported by Sony in collaboration with the PG. What servers it uses and the connection method used are different.

The NaCL client for Chrome does use the same servers as the regular F@H client. So as best as I can tell, it also uses an HTTP connection and might run into the same connection issue.

Constantly reinstalling the client is not going to fix your network connection problem.
