Work fails to download more WU after finishing uploading.

[Sandman192]

The problem goes away after every restart of my computer.

I have not seen this problem on older versions of F@H. F@H v 7.6.13
Hasn't download for 2 days with no work running. Sometimes for CPU sometimes for GPU work. This has happened on 3 of my computers. 1 of which I've stopped using all to gether.
There's over a hundred of these saying the same thing in a row. "10053: An established connection was aborted by the software in your host machine."

10:36:57:ERROR:Send error: 10054: An existing connection was forcibly closed by the remote host.

[Joe_H]

The 10053 and 10054 network error messages are local and not connected with downloading a new WU. From prior experience those are reporting the local network connections to Web Control and FAHViewer being closed.

Things to check would be changes to the firewall and anti-malware settings especially if there has been updates applied recently by Windows Update for instance.

[Sandman192]

I said this has never happened to older versions of F@H. And the problem always fixes its self after every reboot.
No anit-malware and firewall and anti-virus is from Windows. If it was then restarting my computer would not allow more downloading.
If it was from a Windows update then you be having it too on your Windows machine. Again it started when I updated to the newest version of F@H.

[Joe_H]

This has happened to others in the past, both for older versions and the current version of the F@h client. You have also only provided a bare minimum of log information, not a single instance of a WU request failing.

As for updating, you may have to re-identify the FAHClient executable as being an exception, that executable would have changed when you updated. The Windows antivirus counts as anti-malware, so does the Windows firewall. From other Windows users, communication done by FAHClient does need to be in the "Private" zone.

So, post the first 100-200 lines of your current log to show the system, hardware and client setup. And post a section showing an actual WU request failing and we can look at it further.

@Joe_H ... Fairly sure the 2nd code window of OP shows this ... if you see at the end it looks like it might be one of those "established connection" not doing anything errors ... It connects and "starts" download after which nothing happens.

@Sandman192 ... I think what may be happening is that the download connection is hanging for some reason and this is not being spotted/cleared by client - if I am right and you are using windows you don't need to restart client you can just drop the established connection - next time this happens try using TCP View to drop the hanging connection - Fairly sure someone posted a Linux equivalent tool a while back.

[Mxyzptlk]

I have seen the same exact issue on two of my computers.

What is the reported value for CWD near the top of FAH"s log? Are you using the shortcut provided at install time?
Please see below about posting FAH's log.

I have. It's in the first 3 line in the quote and the second quote in the last line.

@Joe_H ... Fairly sure the 2nd code window of OP shows this ...

Think you for understanding.

Using WiFi.I found out for some reason my "Gaming" router is suppose to be good for giving out strong single connections for WiFi and it seems to sucks even at strong single (It's 20ft or so from my router. I';m glad I have my modem/router and connected to it and it's working fine now.

As for restarting my computer which restarts my WiFi only last long enough to download new work and has trouble after a day even though it's connected and still has a good single.
Could it be F@H not liking certon WiFi routers??? That seems very wired and odd and the first hardware to software bug ever.

I have seen the same exact issue on two of my computers.

Are you using WiFi? And if so, what router are you using?
Mines a Netgear XR500 and uptodate. V2.3.2.56

[Joe_H]

Could it be F@H not liking certon WiFi routers??

Not so much certain WiFi routers as not liking network connections that are not reliable and stable. If the connection drops packets, especially ACK packets, the connection can stall with each side waiting on the other. The code to detect that kind of stalled connection has become better over the last few versions, but does not always catch the the condition and do a retry.

With a "gaming" router, its default network settings may prioritize sending and receiving packets used by games. Whether that is at the expense of the TCP packets carrying the HTTP data might take digging down into the documentation or hooking up a network analyzer.
