I don't want to complain, but I still can't validate my workunits...
19-1-2015 23:03:59 | Einstein@Home | Sending scheduler request: To report completed tasks. 19-1-2015 23:03:59 | Einstein@Home | Reporting 73 completed tasks 19-1-2015 23:03:59 | Einstein@Home | Requesting new tasks for NVIDIA GPU and Intel GPU 19-1-2015 23:04:11 | | Project communication failed: attempting access to reference site 19-1-2015 23:04:11 | Einstein@Home | Scheduler request failed: Server returned nothing (no headers, no data) 19-1-2015 23:04:14 | | Internet access OK - project servers may be temporarily down.
Machine ID is 11708865
73 BRP4G units are uploaded fine last week but fail to validate.
As you can see the server won't even want to communicate.

I'd be complaining like hell if I were you and if this had been going for some time :-). The previous problems were with the upload server but that's not the issue here. There should be no reason why the scheduler shouldn't be talking to you whenever you ask, automatically or via the 'update' button if you want to force a contact. Your client seems to be unable to make contact and get a sensible response, even though your internet access is reported as 'OK'.
The steps in the process are:-
1. Completed results get uploaded to an upload server which just stores the files.
2. Your BOINC client subsequently attempts to 'report' the uploaded results.
3. Other backend processes can use the 'reporting' step as a signal to retrieve those particular 'stored' results and move them further along the result processing chain, ultimately getting them to the validator.
It would appear that all your results are successfully uploaded but for some reason step 2. is failing. Of course, validation can't even be contemplated until the tasks are 'reported' so you need to get step 2. happening by manual intervention if necessary. I would be going to the projects tab in BOINC Manager, selecting the Einstein project and clicking the 'update' button every 10 minutes or so until you get the scheduler to properly respond.
Your computers are hidden and even though you have provided a hostID, that only lets me see that you have 73 'in progress' results. It doesn't give me a link to the scheduler contact logs which would give the last successful exchange between your host and the scheduler. It's a bit of a long shot but perhaps you could take a look and tell us if there is anything of interest in that log?
Cheers,
Gary.
@aad: the last scheduler
)
@aad: the last scheduler reply for your host 11708865 got logged on the 7th, so almost two weeks ago. It seems your BOINC client is indeed not able to communicate with the project scheduler.
Please check your private messages for what to do next.
Thanks,

Thanks Oliver,
Did that, but I can't get the email through.
It got bounced even if it is zipped and made plain tekst.
Maybe the email adress is wrong?

I'll forward this.

You can work that out:

RE: You can work that

Only if you're more persistent than I was. I took a look at how the URL is constructed by using one of my hosts and I saw the numerical bits were nnnn/nnnnxyz - I was looking at a seven digit hostID and made the erroneous assumption that it was the first 4 digits with the whole value as the final step in the path. I wasn't dedicated enough to keep trying other combinations such as the whole hostID minus the last 3 digits for the first bit of the path. I figured if someone wanted to hide their computers then they should learn how to check these logs for themselves :-).
Thanks for the tip on how to do it for hidden machines.
Cheers,
Gary.
I got the scheduler request
)
I got the scheduler request file. Unlike I expected, the scheduler doesn't crash on that request, it just acts normally. It really looks like your requests simply don't get through.
The good news is that your 73 tasks have been reported, you'll be credited as usual (pending validation).
The original problem has not been resolved, though. Please try a project reset. You don't need to be afraid anymore that finished tasks get lost.
If that doesn't help, there are certainly people here that are more competent in helping you with debugging your client's http communication than I are with my limited time.

Strangely the machine
)
Strangely the machine reported the 73 tasks and got new tasks according my accountpage.
On the machine itself the 73 old tasks are still there and no new tasks....
Since they are reported it is save to do a reset on this machine now.
Sorry for the wingmen of the new tasks (which I didn't actualy got!)
Or maybe they will be reassigned to me.
Thanks for looking into this anyway.

RE: Strangely the machine

Something has obviously changed after you posted the above. The tasks list on the website shows all 73 'old' tasks - the vast majority as validated - and a bunch of new tasks, one of which has already been crunched and returned so your machine must have the new work if you are actually crunching it :-).
Is everything fully resolved now? I presume the 73 'old' results are no longer showing on your host and you must be able to see all the new ones? What did you do to 'break the deadlock'? :-).
Cheers,
Gary.
The change in the DB that you
)
The change in the DB that you see on the host & and account page happened by me manually feeding the scheduler request that I got via eMail into the scheduler, originally with the intention to debug a possible crash of the scheduler.
The host didn't yet actually get through the normal way. When it does, even after the project reset it will get the "new" tasks the manually called scheduler assigned to it as "resent lost" ones.
