No GPUs available after Windows update

Posted: Thu Jun 12, 2025 8:16 pm

I've been folding on my RTX 4080 for about a year now with no issues, but last night my computer installed a Windows update and now there's no GPU available in the resources. I've restarted again, reinstalled the FAH client, and updated the Nvidia drivers, but still nothing shows up.

Here is the current log:

Your DNS is not resolving fah related addresses.

I'm not sure why that's happening since I can ping the server from the same machine just fine. There's still the problem of the GPU not showing up in resources.

GPU is not showing up because of the stupid gpus.json update policy. your dns is not resolving gpus.txt url.
change to google dns for a minute for client to download gpus.json file

Alright thanks, that resolved the GPU issue, I can add it to a group again. However, now it's stuck in an Assign Wait loop if I try to start folding.

Have you changed to Google DNS addresses?
Also, if you are on wi fi, FAHClient seems to start before any wi fi connectivity initialises, thus it cannot ping the server

Yes, that was after switching to Google's DNS addresses (8.8.8.8 and 8.8.4.4). I am on wifi but I started the client well after the connection was made.

There has been some cloudflare outages recently, it is possible you might have been caught in that
