Issues With Connecting To Servers

[Tweston]

I have been using Folding@home for years with over 45 million points but recently I have had issues with connecting to servers within the Folding@home network which started around the time the new client version came out. I think there may be a bug in the new client that was recently released.

The errors I am receiving is below.

04:00:55:W :CON20:DNS lookup failed for assign1.foldingathome.org
04:00:55:E :OUT20:Failed response: CONNECT

Another Error I am receiving is.

21:39:45:I1:WU13:Downloading WU
21:39:45:I1:OUT71:> POST https://ds01.scs.illinois.edu/api/assign HTTP/1.1
21:39:46:I1:OUT71:< HTTP/1.1 503 HTTP_SERVICE_UNAVAILABLE
21:39:46:E :OUT71:HTTP_SERVICE_UNAVAILABLE: {"error":{"message":"Please wait","code":503}

Is there any way to fix this? I have been using Folding@home for around 7 years and never had any issues until now with this.

Please try the latest beta.
https://foldingathome.org/beta/

[Tweston]

That fixed it, Thank you for the solution. It must have been the previous client version that was causing that error.

Your allow/deny settings are backwards, but I don’t think that is your problem.

I can easily ping this hosts and opening them in web browser is fine.

What does the client use for DNS resolving?

[calxalot]

Custom cross platform code. There were problems trying to use libevent dns.

Does dns always fail for your fah client?
Is it possibly a firewall?
Fritzbox has been a problem in the past too.

[calxalot]

What version of Windows?

[Duce H_K_]

Windows 11 Pro
Not sure DNS failed somewhere else.
I manually enabled all outgoing connections for FahClient.exe
