Yep. I dug through some BOINC doc, so to get application details, names, versions, etc. in xml format you can request this url: https://universeathome.pl/universe/apps.php?xml=1

It seems to get the actual app path you have to puzzle together the following:

[project master url] + "download/" +
[apps.php.xml > application > name] + "_" +
[apps.php.xml > application > version > version_num] + "_" +
[apps.php.xml > application > version > platform_short]

example for android:

<app_versions>
	<application>
		<user_friendly_name>Universe BHspin v2</user_friendly_name>
		<name>BHspin2</name>
		<id>45</id>
		<version>
			<platform_short>arm-android-linux-gnu</platform_short>
			<platform_long>Android running on ARM</platform_long>
			<version_num>21</version_num>
			<plan_class>android_arm_pie</plan_class>
			<date>17 Feb 2022, 12:52:56 UTC</date>
			<date_unix>1645102376</date_unix>
		</version>
	</application>
</app_versions>

"https://universeathome.pl/universe/" + "download/" +
"BHspin2" + "_" +
"21" + "_" +
"arm-android-linux-gnu"
--> https://universeathome.pl/universe/download/BHspin2_21_arm-android-linux-gnu

Windows: https://universeathome.pl/universe/download/BHspin2_20_windows_x86_64.exe
Linux: https://universeathome.pl/universe/download/BHspin2_20_x86_64-pc-linux-gnu

The inactive apps are not accessible though.

Same problem here. :-(

I use Ubuntu 20.04.3 LTS.

Today i tried a project reset. Now the download is fine.

the same to me, now new PC is happy crunching

For Android, what projects are active and have tasks for Android currently?

I was thinking Asteroids had an Android client but it appears they are down.

My Android devices are running WCG OpenPendemics but it seems that project is not handing out task either. Moo!Wrapper is still on. You may switch to it temporarily.

WCG is moving. There is an announced pause for the project from Feb 14th until April 22. click

I just moved one old machine over from WCG and am getting the download temporarily failed, project backoff issue. Anyone having trouble downloading at the moment?

My issue appears to be specific to this one machine. No issues with any of my other ones. After I aborted the hung downloads I could no longer contact the Universe server at all. I reset the project without any affect, then removed the project but now can't add it back as I can't contact the server... Looks like its off to Einstein for this one until WCG is back. Apologies to the wingmen who will have to wait for the tasks the machine claimed to hit the deadline and resend.

Sounds like you are running an old version of BOINC that has expired security certificates. That would cause communication errors with Universe, why you couldn't download tasks and more importantly why you could not add the project back after reset and removal.

Upgrade to the latest BOINC client with fixed certificates.

I thought that was a Windows only problem, but if not then it is very likely the cause. I am running an older version of BOINC on an old version of Ubuntu. The machine is a 10+ year old laptop that I keep thinking is going to die but it just keeps churning away at WCG tasks. At some point I really need to update to Ubuntu 20.04 and get up to date on BOINC as well, but I'm continually stopped by the thought that its end of life is probably a few months away.

With your computers hidden, I could only make a guess as to your hardware. With Linux, usually the OS takes care of the security certificates.

But that said, depending on what your distro sends for the version of BOINC you are running, some versions shipped with a ca-bundle.crt file and most assuredly if you have one in your BOINC directories, it is outdated with many expired certificates. Also older versions would only check for the certificate bundle locally and not read from the OS with more up to date certificates.

If your distro is still using OpenSSL 1.02 or earlier, that is the issue. That version does not know how to look for unexpired root certificates that are listed later in the source file. It just gives up on the first expired certificate and does not parse out the rest of the file.

You should either upgrade the OpenSSL package to version 1.1.1f or later or install a newer distro that ships with a newer OpenSSL package.

Do that and your comms issues will be solved.

Got a new task on one of my Android TV boxes. Seems like it's back online now.

I upgraded OpenSSL and that didn't do the trick so I did what I should have done a while ago and got that machine (plus one other) upgraded to Ubuntu 20.04. The tasks are downloading and flowing nicely now. Thanks for stepping in and offering solutions to get me up and running.
