CPUs not getting WS Assignments

My Nvidia GTX 1080 Ti 11380 is working great, but my CPUs have been waiting for WS Assignments for at least a day. The computer is an Intel Core(TM) i7-7700K CPU @ 4.20GHz, Family 6 Model 158 Stepping 9 running Windows 10 Pro. The Folding@home client is Version 7.4.4
Here is the salient log file snippit.
09:03:03:WU00:FS00:Connecting to 171.67.108.45:8080
09:03:04:WARNING:WU00:FS00:Failed to get assignment from '171.67.108.45:8080': Empty work server assignment

09:03:24:WU01:FS01:0x21:Completed 1300000 out of 2000000 steps (65%)
Is something wrong on my end or is it the server?

Most likely the cause is on your end. With a 4-core i7, the default settings on the Full slider setting will request CPU:7 assignments and there are few if any of those left. In the future that value will no longer be available. Either set the slider to Medium which will change the request to CPU:6, or set the CPU slot to 6 CPU threads using Configure in FAHControl.
The alternative is installing the public beta, version 7.4.16. That has new code to negotiate with the servers for the highest available CPU count up to the requested number submitted by the client.

Joe_H is right.
The back story is that F@H has issues with 'large' prime number of CPUs, (3 is OK, 5 is iffy, 7 and up are bad) and multiple of them (so 14 is bad even though it is not prime)
In the past, they tested each project and blocked each prime as it failed. Lately they have started projects already blocking primes and multiples of primes.
While they wrote code to avoid primes in your client, it is not yet the stable version. so not many folks have it, yet.

Thanks for your speedy reply.
If I set folding power to medium, will the GPU still run full tilt?

I would use the Advanced Client, then choose Configure, and Slots, then select the CPU slot and press Edit.
Under CPUs it is likely to have -1 selected, which lets the client choose, and I would change it to 6.
Then OK and Save, and then Exit if you are all done.

Got it - thank you guys. The CPUs started folding as soon as I changed to medium power and restarted the client. I just changed back to full power with CPU slots set to 6.
The Nvidia GTX 1080 Ti is a beast. I'm now folding @ (pun intended) close to or slightly over 1 million points per day.

With 1 GPU and an 8-way CPU, Full power on FAHClient 7.4.4 sets CPUs to 7 and Medium sets it to 6.
The GPU is either folding or not folding -- no intermediate settings.
On FAHClient 7.4.16, the client and the server will negotiate the maximum setting that's safe.
If you're actually running that WU with 7 active CPUs, the chances of an early failure are likely. Please don't complain if it fails before reaching 100%. With a setting of 6, it's likely stable.
The whole point of the recent changes was to maximize the chances of a successful completion, even if it only uses 86% of your CPUs.
Actually, there's a minor improvement in GPU speed when your total CPU utilization is less than 100%.
Depending on several factors, you may be really running it with 6 or with 7.

I have two CPU clients not folding for a few hours now, one Mac, one Windows.

Folks are going to look at the title and think "Oh we solved that". You are MUCH better served to start a new thread.
Including the first 100 lines of the Log can give those wise enough to help, the information they need to help.
Best of luck!

I had this happen to one of my computers earlier today, removing client-type advanced from the configuration resulted in a WU download.

Joe, thanks.
Removing client-type got the Mac, Win10 and Win7 CPU clients going.

I did some further checking, WS 128.252.203.4 went down earlier in the day and there wee some issues after it came back up. It appearss to be operating normally now, will look again later to see if there is an y update.

I have one client that is still unable to download from 128.252.203.4 and no other servers are tried. I do not have the client-type set.

After I submitted the above posting, the client downloaded a unit from 128.252.203.2.

During the night, all three of my CPU clients successfully downloaded WUs without client-type attributes.
This morning, I reinstated client-type for my Mac client. Upon finishing the WU, it failed to download a new WU. I soon noticed by the sound of the fan. I removed it and it connected to a different WS and got work.

EDIT: client-type to normal worked
