Exception: Failed reading core package header.

[Matts1984]

I'm looking for some help with my GPU (I have a feeling the response may be that it's too old) but I'm hoping for some other guidance to get this running. I'm not looking for massive performance but just to contribute anything at all. My CPU is folding fine, my GPU is stuck waiting for the FAHCore update:

Looks like some firewall blocking connection? Can you download from the link manually?

[Matts1984]

Yes I can, I tried that to see first before posting. The file downloaded immediately. I have another computer on the same network (same limitations) that runs CPU and GPU folding just fine. I can't find any logs, either on my computer or network logs indicating a block at all.

I also tried a client uninstall, reboot, reinstall, reboot... and still occurring.

Since I can download the file on the same computer, can I simply move it to the appropriate directory?

You can, but it's not perfect and the problem will come back if there is a core update.

I know it might sound stupid, but sometimes, replacing the Ethernet cable helped.
