Project 16525 not uploading

[TonyStewart14]

I have a WU that is not uploading despite other WUs uploading and downloading fine for my GPU. I get the following error for both the work and collection servers:

Any ideas on what could be causing this WU upload to fail? I have tried disabling antivirus and it is still not working. I use Bitdefender and turned off both firewall and Bitdefender Shield. I also tried rebooting.

[Joe_H]

I am not seeing anything obvious to explain this. Both the WS and CS indicated in the log are up and responding from what I can see. Since you can upload and download WUs to other servers that makes some possible causes less likely. If you were posting from someplace outside the US that cold be an issue with some servers, but the IP you posted from indicates you are in the US. It is possible a router between you and these two servers is dropping packets under some conditions. Otherwise the symptoms look just like what we have seen in the past for a firewall blocking connections using HTTP over ports 80 or 8080 and not using a "known browser".

[TonyStewart14]

Thank you Joe for the response. I am on Ethernet and haven't had the same issue with other WUs, so packet drop shouldn't be an issue. I also followed Bitdefender's steps to disable AV completely since there isn't one button to completely turn everything off, but I still had the same issue.

[TonyStewart14]

I have a second WU giving the same error message (156,4,4 in addition to 26, 4, 13). I have been able to finish WUs on other projects just fine with some of the same servers, so I know that's not the issue.

I also had the same problem uploading projects 16525 and 16781 on a computer running BitDefender. The logs below was from when I had both WUs completed but neither one could be uploaded. So the two uploads were happening at the same time and the log entries were a little co-mingled.

However, the same computer was able to upload 12299 without a problem.

20:02:58:WU01:FS01:Cleaning up


After much troubleshooting, I concluded that the problem is with my computer and not my network firewall. Firewall logs told me the TCP connection ended because client (my computer) had reset the connection rather than the normal TCP FIN, which means my computer didn't like the way the upload conversation was happening and unilaterally terminated the conversation. So it must have been caused by some settings or a piece of software on my computer. I tried disabling everything (yes everything not just anti virus) in BitDefender and it didn't make a difference. Finally I completely uninstalled BitDefender and voila both WUs uploaded immediately! There is no log entry in BitDefender that tells me what F@H did that made it mad.

Mystery is still unresolved. I'm still experimenting.

I also had the same problem uploading projects 16525 and 16781 on a computer running BitDefender. The logs below was from when I had both WUs completed but neither one could be uploaded. So the two uploads were happening at the same time and the log entries were a little co-mingled.

The symptoms do sound very like somewhere in BitDefender stateful packet filtering had been enabled on HTTP traffic. A common default filter is to deny HTTP connections when they are not to and from "known" browsers such as Chrome, Edge, Firefox, Safari and so on. When that happens an exception needs to be added allowing in this case FAHClient to do download and upload connections over ports 80 and 8080

@Joe_H...

Thanks for responding. Same computer just completed a CPU job and successfully uploaded the WU with BitDefender fully enabled. I'm running a GPU job on it now.

I hear your theory of BitDefender blocking the traffic due to fahclient not being a known browser but I don't think that was the case at least in my situation. The only place where BitDefender requires a browser to be specifically configured is the Privacy > Anti-tracker function, which installs a browser plug-in to your browser to request the web site you visit to not track you. Most browsers have that function already anyway. I don't have it enabled. I also made sure fahclient.exe is added to the known applications list and any outbounc TCP connections are allowed. Besides, I'm a network engineer and I routinely use non-browsers (curl, wget, telnet to port 80) to access web sites on my BitDefender computer without a problem.

Once the GPU job is done running, if it fails to upload, I will run a pcap and see if I can figure out something from the pcap.

Ok experiment done. Here are the observations:

1, The problem is spec

• • • ific to some WUs. Same computer with BitDefender fully enabled is able to turn in WUs successfully most of the time. But WUs 16525 and 16781 are the two that I am constantly having this problem with.
      
      2, The problem follows WUs and not work servers. Same WU different work server didn't make a difference. Still failed.
      
      3, Completely disabling BitDefender didn't help. Followed these instructions: https://www.bitdefender.com/consumer/su ... wer/28557/
      
      4, Only a full removal of

BitDefender made a difference.


When it didn't work, PCAP showed:
1, The completed WU was uploaded.
2, Work server responded with 200 HTTP_OK with TCP (FIN,ACK)
3, My computer sent back a TCP ACK, which was expected
4, Then without waiting for the server's response, my computer sent a TCP (RST,ACK) to the work server to end the connection abnormally. This was not expected.


When it worked (after I uninstalled BitDefender), PCAP showed:
1, The completed WU was uploaded.
2, Work server responded with 200 HTTP_OK with TCP (FIN,ACK)
3, My computer sent back a TCP ACK, which was expected
4, My computer then sent a FIN,ACK to the work server to gracefully end the TCP connection. This was an expected outcome given the server's request to end the connection in step 2 above.
5, Finally the work server responds with an ACK to my computer's FIN and it was all done.

It seems that something in BitDefender didn't like how these WUs were uploaded. And that something could not be disabled without a complete uninstall. I guess a workaround is to force small units with the max-packet-size=small setting. Does that work on 7.x clients?
