I tried Boinc a few months ago but was never able to attach, so I gave up. Tried again yesterday and after a few attempts actually attached (to Seti). Since then I've been getting connection errors out the wazoo. I've setup my firewall (XP) and set the HTTP proxy server (don't know if I have a SOCKS proxy server).
I connect to the Internet through a satellite. The transfer times are ok but the latency is very high considering the very long distance the signal has to travel. Can this be causing problems? I tried attaching to Einstien today but no luck (Network communication failure).

When I click "Update" an message box appears saying:
"BOINC is unable to communicate with a project and no default connection is specified. Please connect up to the Internet or specify a default connection via the connections tab in the Options dialog of the advanced menu."
Well, I'm absolutely connected to the Internet (satellite is always on). So I have no idea what this means.

It actually downloaded and sent some work to/from Seti but most of the attempts now fail:

Sometimes it works, most times it don't. Any thoughts?

Yesterday Seti had its (delayed) weekly outage, so maybe that you tried to getwork at that time. Don't try at this moment either, as they have yet another 2 hour long outage.

Next time check the front page news at http://setiathome.berkeley.edu if there's news on what is happening.

I brought my computer to work (DSL) Friday (it's a laptop) and bing, bam, boom everything uploaded right away. Now I'm back home and the connection errors continue. I think there is definately an issue with the high latency times of the satellite. The signal goes from my computer, to my sat router, out to my dish, up 22,000 miles to the satellite, down 22,000 miles to the earth station, over to their router, then out to the Internet. Then the whole thing happens in reverse for the reply. This could be a few seconds. I guess Boinc don't like that.

Has anyone discovered what this message

Scheduler request failed: Unrecognized HTTP Content-Encoding


actually means, and whether a solution has been found? I've searched the Unofficial Boinc Wiki and not found this message. We have a BBC climateprediction cruncher with this problem at the moment.

I've still got the same problem using starband satellite isp. I tried the
5.6.4 Boinc Manager but still the same deal. Sometime I communicate fine for
a 24 hr. period or longer, other times can't communicate at all.

I asked David Anderson a while back and this is what he answered:

I haven't seen this.
Sounds like a libcurl issue.
We need to find out the BOINC version
before we can work on it.
-- David


Upon learning that the person I was trying to help used 5.4.11, this was the further communication:

Have him set the <http_debug>1</http_debug> flag in cc_config.xml,
and send the resulting stddae.txt file.


The various threads looking for these (and other) errors are spread thin, mainly on here, Seti and Einstein, but you can pick up the link and take it along to the CPDN forums and post it there.

I had one person with the BBC Climate Change Experiment send me his files, which I dutifully sent on to David and Rom. And never heard a further thing.

So I am as informed as the next person. ;-)
