I wanted to follow Nvidia's call to action to donate unused GPU computing power to fight against COVID-19 and installed the Folding@home Client at Version 7.5.1 on a Windows 10 x64 machine.

My logs are full of messages that read:

ERROR:Receive error: 10053: An established connection was aborted by the software in your host machine.

What am I doing wrong and how can I resolve this?


That's the start part of my log:

I am now also seeing errors of the form:

    I know it's cliché, but when either my CPU or GPU is sitting idle for too long, I get a lot of mileage from pausing and restarting the FAH Client. Or restarting the computer. That seems to prompt the client to try downloading again, and sometimes it finally works. – Lorien Brune Apr 2 '20 at 2:11

    Note that Rosetta@Home also has COVID-related projects, if you get fed up with FAH. Don't give up on helping in some way just because FAH is overwhelmed. There's plenty of work (units) to do! – Lorien Brune Apr 2 '20 at 2:13

Just wait and let the application idle. At one point, you will get work units.

(Additionally, it may help to restart the application in order to force a try of a download.)

Folding@Home announced via twitter:

Why has my machine not received any work units (WUs)?

We have been overwhelmed with support and donations, so our servers had to suddenly accommodate a large number of returned WUs. We are working on expanding our memory. Please bear with us as we address this surge.(3/8)

I let the application idle for hours, and at one point it took three CPU-bound tasks (one at a time, idling in between). Starting today, it took one GPU-bound job.

I assume the error message relates more to the local webinterface and is of no indication that the application itself is misconfigured.

In Windows, when you install the client, you are presented with a Windows Security Alert, like in this picture:

Windows Firewall Sample

You need to allow access for both networks. That is, the "Private networks, such as my home or work network" needs to be checked. So, if anyone encounters this error a hassle free solution is to fully uninstall it and install it again. Otherwise, go to Control Panel > System and Security > Windows Defender Firewall > Allowed apps > Change settings and allow fahclient for both networks.

  • I'm not sure "public networks" is actually required. This error persists on home network too (when public is not active). Anyways, you don't need to reinstall to try it. In Windows, for example, goto Firewall and then click "Advanced Security". Find fahclient in list for inbound and outbound. Double click the entry, then hit the "Advanced" tab. Here you can add both "Domain" and/or "Public" attribs to the rule. If the error persists, be sure to turn back off those attribs. – dhaupin Mar 29 '20 at 22:41
