Can't report tasks or fetch scheduler list on Mac OSX 10.5 (PPC)

(moderation:
Hi.
My Mac G5 has been trying to report a couple of completed Binary Radio Pulsar Search tasks for the past few days but has been unable to contact the server. A typical entry in the Event Log is:
Thu Mar 31 10:09:15 2016 | Einstein@Home | update requested by user Thu Mar 31 10:09:16 2016 | Einstein@Home | Fetching scheduler list Thu Mar 31 10:09:28 2016 | | Project communication failed: attempting access to reference site Thu Mar 31 10:09:41 2016 | | Internet access OK - project servers may be temporarily down.
Is this due to an ongoing problem at the server end or do I need to do something about it here? Can I do anything without losing the task reports?
No uploads waiting. No new tasks since 21st March. No problems with other projects on the same machine. No problems with E@H on my other (younger) Mac.
Macintosh G5
Mac OS 10.5.8
BOINC 6.12.35 (PowerPC)
Binary Radio Pulsar Search (Arecibo) v1.58 (ALTIVEC) powerpc-apple-darwin

I would suspect that the old OS does not have the root certificates to communicate via SSL to the Einstein@home server. This was reported in one of the Debian related threads for an older Mac too. You can activate some log flags (Client Configuration) on your Client. In particular: http_debug and http_xfer_debug (I hope they are recognized by 6.12.35) to verify this or find another problem.
Hi Christian. Thanks for

Hi Christian.
Thanks for your reply.
LadeSchale's suggestion in that other topic was to change 'https:' to 'http:' in the scheduler URL 'https://scheduler.einsteinathome.org/EinsteinAtHome_cgi/cgi' in E@H's client_state.xml file. But in fact the current entry on both my machines is 'http://einstein.phys.uwm.edu/EinsteinAtHome_cgi/cgi'.
I added the and tags to the G5's cc_config.xml file and started up BOINC Manager again. There does appear to be an SSL connection error, both at start-up and during E@H updates:
The log from an update request is listed below, error points highlighted in red.
I may try changing the scheduler URL to the one in LadeSchale's post, but I'm not sure what the consequences will be for my results if they're reported to the wrong server…!

Your Client tries to connect using an probably outdated encryption algorithm. I don't know if you can update the Client but you should. Changing the scheduler URL will not help because you will get redirected to SSL again.

BOINC 6.12.35 is the last client that'll run on a Mac PPC. If Einstein@home's changed its server software so that G5s can suddenly no longer connect with it, it's up to Einstein@home either to issue a fix or to announce that G5s are no longer supported. Whichever it is, it should be done quickly.

I found other hosts with the same BOINC and OS version that could connect recently so it seems to be another issue. Maybe you are missing an update that provides the updated encryption.

My two unreportable tasks, received the day before the server replacement, reach their deadlines today.
There's no indication that Amanda Finnegan's machine has fared any better since she complained. But like mine, it's had no problem communicating with SETI@home.
Donald A. Tevault's problem in the previously linked post appears to have been overcome at the time, but his G5's "Last contact" still predates the new server. However, his G5 hasn't apparently contacted any of his other projects in the past 30 days, so maybe his situation's different.

The problem is the rather old

The problem is the rather old BOINC Client that is lacking certain security updates that we now enforce on Einstein@home by using up-to-date SSL certificates (which AFAIK Seti@home does not). Probably only a rebuild of the 6.12.35 Client using a newer openssl library is needed to get it working again. You need to ask the BOINC Mac OS X developer about that (via github or email).
RE: You need to ask the
)
I've wasted enough time on this already. BOINC projects are just research efforts my computers help out as background tasks. Finding out how to use GIT or joining a mailing list, trying to persuade a busy developer to recompile a client on a platform for which support was dropped four and a half years ago, and hoping to get the result before Einstein's developers pull the one remaining ALTIVEC app because there are no G5s communicating with the project seems particularly futile. ;)

I'm running a BOINC Client 6.12.35 on a Xserve G5 with Mac OS X (Server) 10.5.8 without problems uploading, reporting or fetching tasks.

RE: I may try changing the
)
There is only one server (i.e. scheduler), that is pointed to by different URLs. For the time being this suggestion should indeed work. My Client apparently works because it is still using a pretty old scheduler URL that gets redirected to "http://scheduler.einsteinathome.org/EinsteinAtHome_cgi/cgi".
The BOINC Client links the system's SSL library, thus compiling the old Client with a new Curl version as Christian suggested (or a newer Client code) wouldn't help. What needs to be updated is the system's SSL library, or a Client would need to be compiled with an own, static, newer version of the SSL library. I'll see if I can get this done, but probably not in this or next week.
That's the curse of using/supporting an outdated, unsupported end-of-life OS.
