I have 30 completed tasks but I keep getting a message that the Project has backed off the upload. I've checked the server status but that says everything's running. Any ideas?

As already posted here https://asteroidsathome.net/boinc/forum_thread.php?id=943 and here https://asteroidsathome.net/boinc/forum_thread.php?id=944 the SSL certificates expired. Until they are renewed a connection to the servers can not be established.

well, given that your browser should given you a HUGE warning that this website certificate has expired and can't be trusted, you should have a pretty good idea of what is wrong ;-)

I just ignore that utter nonsense. How is it going to become unsafe because the certificate is a couple of days out of date, but it was ok a week ago?

Well, this is basic web security. Yes, it is not less secure, as the connection is still encrypted. That being said you should never trust a connection with expired certificates. There is a reason why those have an expiration date.

How do I tell Boinc to just go ahead?

I guess you could try some trickery to get this working. Maybe there are some settings you can change in client configuration or you need to set up a custom proxy. But again I would advice against that and simply wait till the certificate is renewed.

I'd like an explanation of how a website can become dangerous in literally one second. How can it be safe now, then not safe one second later? What's magical about these certificates? How can they prove a site is safe for the whole sometimes 10 years the certificate is issued for? It's like me getting a driving license which expires in 50 years, then saying I must therefore be a safe driver in 50 years, but in 51 years, I'm dangerous. Nonsensical.

It is not the website becoming dangerous once the certificate expires. It is more about trust I guess.
The certificate gets issued by a trusted third party for a given time frame. If the certificate expires/is not renewed you can no longer be sure, that the website was not taken over by someone else.
Your driving license example might not be fitting in this case. Maybe a passport would be more accurate. If your passport is stolen it can only be used by a bad actor until it expires.
A 10 year validity is really unusual by the way. Usually it is only one or two years (or even shorter).
I can understand that this is annoying, but this is something the project administrators need to get a grip on. Especially as things like https://letsencrypt.org exist.

I don't follow guidelines on safety. I'm sick of this happening every couple of months to one project or another. I want it turned off. What do I need to sign in blood to make this happen?

This is a really bad idea, especially, as you are executing code on your machines, that is downloaded from the internet. If you really want to, I am sure, you will find guides online, but I won't provide instructions.

@Kyong

we've already sent PM and email to the project admins.
keep in mind that this is a university project so TTR* may vary :)

*Time To Resolve

In the meantime, nothing is lost, just queued.
keep crunching
Hopefully they'll increase the deadlines if it comes to that

"the instant the server comes back"

that's not how it works

It may take several days to clear the backlog

Certificate is renewed. Happy crunching :)

I'm can't crunch because I'm out of work. I only hold a 1 day queue.

Deadlines are irrelevant, that's not how Boinc works. When I haven't sent a task in on time, the server will at some point give it to someone else, say you. If I then hand it in late, but before you've started it, your computer will be instructed to abort. I will still get the points. If you complete it before me, you get the points and I don't.

But in this case, mine will be returned the instant the server comes back into availability and there's no way a resend could get done first, so I lose no points.

The only stupid thing about this is if I return the result after you've started the resend, it lets you finish it, wasting your electricity and computing time which could have been on another task. The reason? They think it might upset people if they were halfway through a task and it was aborted. How utterly absurd. If need be give them partial points for their time.

Wow you're really taking this seriously aren't you ? chillax...

and in that particular case;
1- the server wouldn't give your WU to anyone since nobody could connect
2- given that a manual operation was needed to restore connectivity (SSL renewal), another manual operation "could have" been done to extend deadline (maybe)
3- since you have nothing to crunch, you could just power off your machines and wait it out. or participate in another of the 10's BOINC project :)

anyway, we're back, no big deal here ;-)
