Got it on only a single of my Hosts (Link) :

SETI@home 26.09.2009 19:33:17 Started upload of 26au09ad.14272.14791.14.10.220_1_0

--- 26.09.2009 19:33:31 Project communication failed: attempting access to reference site

SETI@home 26.09.2009 19:33:31 Temporarily failed upload of 26au09ad.14272.14791.14.10.148_0_0: HTTP error

--- 26.09.2009 19:33:33 Internet access OK - project servers may be temporarily down.

I already tried resetting Project, updated BOINC from 6.4.5 to 6.6.40 but it doesn't change anything.
Network connection is fully normal, a quick run of POEM resulted in absolutely normal behaviour.
I even tried flushing the DNS cache and did several System reboots - all to no avail.

All my other Systems running over the same pipe have no problems running and Down/Uploading SETI work.
Basically it can download work, process it but can't upload.
BOINCview shows 100% Upload complete where it aborts and backs off over and over.

Does anyone know such a weird behaviour with SETI only and possible fixes (?)

Yes, I do. For me, it started in November 2007. Since then one of my laptops needs HTTP 1.0.

To switch from HTTP 1.1, you must create a text file named cc_config.xml in your BOINC data directory (if it doesn't exist already). The data directory is mentioned in the message tab of BOINC manager after a restart of the client.
With notepad or a similar text editor, enter (copy&paste) the following into that file:

  <cc_config>
    <options>
      <http_1_0>1</http_1_0>
    </options>
  </cc_config>

There are no lower case 'L' characters in that code, only digits '1'. More information about cc_config you can find here.
In BOINC Manager (Advanced view) select menu 'Advanced->Read config file' to activate the new configuration.

Computer sind nicht alles im Leben. (Kleiner Scherz)

SETI@home classic workunits 3,758
SETI@home classic CPU time 66,520 hours

Awesome, that did the trick.

I already had this file in the BOINC data directory after installation on the System years ago, but somehow it got lost (?)
(would have never thought of that File going AWOL, rather searched everywhere else).

Thanks for the quick help :)
