Upload Issues to 3.133.76.19:80

[PantherX]

...my firewall was seeing something coming at it from 3.133.76.19 at the end of the upload sequence that it did not like the look of...

Pretty sure that it would be this message:
02:44:06:WU00:FS01:Upload 98.23%
02:44:08:WU00:FS01:Upload complete
02:44:08:WU00:FS01:Server responded WORK_ACK (400)
02:44:08:WU00:FS01:Final credit estimate, 85469.00 points

Thank you PantheraX, 37 minutes after I posted this the WU uploaded for a final score of 157K

Glad the result got returned, at least now i know what to do if I see this behaviour again.

I think it would have to be something else, PantherX, probably at a TCP/IP level rather than payload content, since the firewall was clearly throwing a hissy fit at it. Of course the server almost certainly is not sending plain text. Maybe I should wireshark it to find out. I don't suppose the protocol is published.

I will try removing the exception today and see what happens!

@G3WGV

Your firewall setting or not, that specific server 3.133.76.19 just sucks. I have no harsh firewall restrictions and am connected with a very fast and reliable connection. My bunch of folding servers have absolutely no issues with down- or uploads, any final FAH result file is uploaded with ease in seconds, no matter what size.

The only exception is that specific AWS server, 3.133.76.19, that piece of ... does only respond after many tries and upload speed is always slow as on my first times in internet, back in the 1990s. And these are not single issues anymore, rather daily business as soon as 3.133.76.19 steps into the game.

And unfortunately it's always good habit here to blame the donor having anything wrong on its side ...

I'm experiencing the same behaviour on this server again

The protocol is published, all transfers between clients and serves are done over HTTP on either port 8080 or port 80.

It's more experience than habit, and there's also a lot of "internet" in between you and the server, which can be the cause of failures (that are hard to analyze and remedy).

That said, 3.133.76.19 really is a repeat offender and should be looked at.
It used to not have a collection server iirc, now it has one but it's "not connected" according to https://apps.foldingathome.org/serverstats.

I turned off the firewall exception but then enjoyed something of a charmed existence for most of today, getting allocated to other WSs. Eventually my luck ran out and I got a big job (94MB upload) from our errant WS. After 25 minutes of failed attempts it sluggishly uploaded and... success! Server responded WORK_ACK (400).

The problems with this WS are well known and have existed for a considerable time. It seems a bit pointless (creditless?) expending GPU work and electricity on WUs that cannot be uploaded in a timely fashion. Can't something be done about it?

[TPL]

I've had many WUs from 3.133.76.19 and never had any problems.

Edit: checked log and in one case 3 unsuccessful cases to upload on port 8080, then successful upload on port 80.

I'm having issues as well for the past few days. Any update on this? Below are the logs.

How did you specify which port to use? Mine keeps erroring out on port 8080. I'm also pretty confident my firewall rules are perfectly fine and I only have issues with this server.

[bruce]

You don't specify which port to use. FAHClient is totally responsible for the upload IP and Port. 8080 is tried first and if it fails, it reverts to 80.

This might matter if you've configured FAH to use a proxy server but that's an unusual situation for home computers.

[bruce]

Based on the frequency of reports on this forum, this is FAH's most troublesome server. I regularly file a report with the folks who manage these servers. They generally fix something and it works for a while and then before long, the troubles start again.

I don't have enough information about the specific problems to make any useful comments about how to fix it permanently.

[SirTj]

Yea, I don't have a proxy server running at home. Apparently, it keeps trying on 8080 and never switches to 80.

From the logs, it does seems like the server is dropping my connection after receiving the initial upload. I also notices that the server was recently restarted with the uptime being only 3 hours. It's still having errors receiving my upload.

Any idea what I should do next?

BTW, my local PC time is 04:49.

Get some sleep and don't worry about it until later.
