502 Errors downloading SETI artifacts

After Feb 3rd, my cell phone's ISP relaxed the bandwidth restriction.
I can download and completed Einstein@home workunits, but SETI@home still has a problem, I've been unable to download a workunit (or the SETI client in that whole time.

I turned off GPU processing, turned off astropulse, but even small workunits aren't being downloaded, so I'm not sure what to try next. I've tried resetting the project, detaching and reattaching.

It seems that I'm stuck trying to download the SETI client itself. I've alternatively hit the .13 and .18 servers, with no change in results.

HTTP 502 errors are noted whether I use wget or the BOINC setup:

Exit BOINC.
Download the Seti application by hand, put it in your BOINC Data directory/projects/setiathome.berkeley.edu/ directory. Link http://boinc2.ssl.berkeley.edu/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu

Restart BOINC.

Where your data directory is depends on how you installed BOINC. From the Berkeley installer, or from the package manager.

Real is just a matter of perception.

OK, downloading using those link do NOT work.

(It seems identical to the link that the BOINC client is using.)

How can I obtain the binaries? I tried these three types of link:
Main address:
http://boinc2.ssl.berkeley.edu/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu
Server 1: http://208.68.240.18/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu
Server 2: http://208.68.240.13/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu

I have connectivity, ping to 208.26.240.18 returns a response, no dropped packets.

What seems to work is using the Coral CDN, bypassing the SETI@home site altogether. So http://boinc2.ssl.berkeley.edu.nyud.net/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu downloads OK

My theories are:
1) My ISP is putting some half-assed, broken proxy server between myself and the servers at Berkeley.

2) SETI's network infrastructure has blacklisted my computer somehow.

The problem is, once I download the binaries, how can I be sure that workunits will download properly? Can I force HTTPS connections or otherwise work around my ISP's brain-dead proxy?[/b]
____________

I was able to download the executables and most of the support files using the nyud.net hack (listed above).

This does not work for workunits, since the BOINC setup must do that.

How can I convince the SETI@home server boinc2.ssl.berkeley.edu to let me have those? Everything I try to download directly from it suffer the same 502 fate.

It seems like a bad proxy should affect ALL projects, but einstein at home and others are working fine.

Try to set some free Proxy by your choice in BOINC Options
