I would like to report a problem with servers not accepting or whatever the rue nature of the problem is. This is part of one of my client logs that shows what is happening. I have partially discussed this in another thread I created about problems with a WU.

[15:58:11] - Couldn't send HTTP request to server
[15:58:11] + Could not connect to Work Server (results)
[15:58:11] (130.237.232.237:8080)

[16:38:20] - Couldn't send HTTP request to server
[16:38:20] + Could not connect to Work Server (results)
[16:38:20] (130.237.232.237:80)
[16:38:20] - Error: Could not transmit unit 03 (completed November 13) to work server.

All for of my systems are setup the same and this does not occur with all the systems nor all the time with this particular system. It was commented in the one thread I started about problems with a WU that it took over 5 days to return a WU and I only received base points for it. Not true, I posted the log for that WU and it showed it being returned in less than 5 days. Additionally, Grandpa stated based on part of log I posted that the server was not communicating back with my system that the WU had been received. This is not a problem with my hardware but with the upload servers. This has already cost me almost a million points and I do not feel I should continue to be penalized for a problem that I have no control over. Please advise. Thank you.

I see you've gotten no response. I have not been on the forum for a couple of days so I'm just checking to see if some action has already been taken or if this still needs attention. You did get credit for a 6904 not long after you asked the question so it's likely that's the WU that you were looking for.

Thank you for the response. However, I need some help with what seems to be the root of my problems. Here is an excerpt from one of my logs:

What is happening is this continues on and on until I reboot the system. At that point I will get an entry "Attempting to send results", then I will download a new WU. During processing the new WU, it will periodically give an entry retrying to send unit until eventually I will get an entry to the effect "this WU has already been received. I am getting credit for the WU at this time even though my systems will continue to try to upload them.

As an update, here is a continuation or the log posted above. I would like to note it only does it with the 6903 and 6904 WU's. I have no problems with the 6901 and SMP WU's. I have a 7MB DSL line with 1MB upload speed, as someone had mentioned in another thread it could possibly be my internet connection.

So at this point I did not get credit for this WU. [22:17:15] Project: 6903 (Run 8, Clone 9, Gen 29)

Posted: **Wed Nov 23, 2011 4:00 am**

No. P6903 (R8, C9, G29) is apparently still stuck in queue for you. Thus, no credit yet. Could your DSL carrier be capping your upload file size?

Posted: **Wed Nov 23, 2011 4:42 am**

No on the upload file size restriction. They actually advertise it as being larger than what I posted earlier but I have confirmed with a 3rd party bandwidth tester it is not.

I have an update, here is a continuation of the log that shows it finally uploaded. So what is the problem here? It is not Internet connection, I have ruled out OS, FAH client and setup. Would you please consider that the server is having some type of issue?

I will end this thread since no one cares to step up. All of a sudden my servers are magically connecting and sending the WU's with no problem. Thanks for nothing. I know, it was my hardware and it magically fixed itself.

Posted: **Sun Nov 27, 2011 10:23 pm**

Hovart if anybody on this would have been able to help they would have. Sorry you feel you were neglected but nobody had a answer to your problem.

Posted: **Sun Nov 27, 2011 11:47 pm**

Thank you Grandpa. It seems it was not a matter of me needing the help. I think it was a problem with their server. If I changed nothing on my part on 4 separate computers that were all having the same problem, and now they all upload properly, the problem was not mine, it was the PG servers. That was the inference of my last post.

Posted: **Mon Nov 28, 2011 1:19 am**

The problem could have been any of the numerous hops between your router and Sweden, where the server is located...

I'm not sure of your level of technical knowledge, so I'm writing a fairly comprehensive post that may be overly informative.

In any event, from your logs I can see that it took your machine over 45 minutes to attempt to upload the larger work unit to the server. That indicates an upload speed of less than ~35kB/s, or ~.285Mbit/s (as we do not know how much was uploaded in that period and assumes that the file size was ~100MB). Given your upload speed is at least 1Mbit, confirmed by your third party app, there is a bottleneck somewhere between your router and PG. The smaller file size of the 6901 work unit means that it is likely that uploading at this rate still allowed it to upload in a decent amount of time.

Reasons to suggest it wasn't PG's servers is that there wasn't a lot of other users posting in this thread reporting similar experiences, yet all your machines were experiencing an issue and they were experiencing it continuously for an extended period of time. If the bottleneck was at PG's server, or their network connection to the outside world, then all users would be affected and all would be unable to upload their work units. Four machines in one location failing to connect and no systemic reports of issues from multiple locations globally != immediately suggest that the problem is with PG servers. Rather, it points to an issue with the connection between the one location and the servers. Indeed, the lack of other people reporting an issue tends to suggest that the issue is closer to your end than it is to PG's as the closer the issue is to PG's server, the more people will be affected. (If the problem was the interconnect switch between Sweden and France, all US and donors from many other countries who's ISP has interconnect deals with a carrier that routes to Sweden through that switch in France would be affected.)

As I said, any number of reasons could cause an issue between your location and PG's servers - 99% of them being out of PG's hands. For one thing, most speed-tests tend to measure only the distance from you to your ISP (or their closest testing server to you). Testing from you to an overseas location, such as trans-Atlantic - often yield slower and fluctuating results. This can be due to an interconnect being faulty and causing odd routings that degrade performance, due to your ISP not purchasing enough carrier bandwidth to accommodate demand or due network congestion on one or more hops, amongst many.

The issue magically resolving itself leads me to suspect that there was an issue somewhere between your router and PG that was resolved. 'Magical connecting' != mean that PG fixed something without saying anything, it means something was fixed somewhere. It does not conclude that the issue was PG's servers.

But then this is just the view of someone who'd be blinded by the loss of light if Pande Group comes to an abrupt stop.
