I have 3 identical (except for memory) SBC systems running Windows 10 and dedicated to running BOINC (V7.16.11 x64). They have been running for well over a year with no issues. Recently the 3 systems updated WIndows 10. Now BOINC on one of them cannot access the internet. The internet is accessible from the computer as I can access the internet with a browser. I can also use a browser to access the URL BOINC is trying to access with no issues. I have uninstalled BOINC and removed all of the data files. I tried both the 32 and 64 bit versions and both won't work. I use Windows firewall and the BOINC tasks are allowed access to the internet. Anyone have any ideas?

Never mind. I stepped away for a few hours and came back and now I can add projects again. What changed in those few hours to make it work I have no idea.

Well, it is failing again. After downloading some tasks it now says it cannot access the internet. I am also getting this on another SBC computer. The internet is reachable from these devices as I can access the internet from a browser and even access the URLs that BIONC is trying to access. BOINC tasks as allowed access to the internet from the Windows firewall. Any clue on how to troubleshoot this?

You're talking about "SBC systems", is that anything to do with a software or other company? Because if that's so, and these run in the company, it's the company firewall that blocks these communications and you'll have to take it up with IT to get past that. After you asked your boss if it's all right to run BOINC on these computers.

I'm fairly sure what he meant with "SBC systems", is he was using the common acronym for "single board computer", i.e. Raspberry Pi and its ilk.

Too many TLA's

Three Letter Acronyms.

Yes, I was speaking about Single Board Computers. These happen to be Intel based from HardKernel- model ODROID-H2. I built 3 of them in a single PicoCluster case (they make a nice kit which includes power supply and network switch) and am running Windows 10 on them.

I finally got them working again by uninstalling the 64bit version of BIONC and installing the 32bit version. Why it suddenly stopped working or why the 32bit version works and not the 64bit version, I have no idea.

Sorry for not responding sooner as I did not receive notifications of prior postings.

Only 32-bit versions of BOINC working, and 64-bit versions failing, on low power intel CPUs is a known problem, and we know how to work round it.

Hold on while I look up the earlier references.

Noting for future reference: https://github.com/BOINC/boinc/issues/2470

To decode the rather obscure language in that reference: we found that 64-bit BOINC crashed when it tried to access 'secure' (https) websites. This was due to BOINC being distributed with old versions of some security files.

BUT: that was in 2018. A change was made at the beginning of 2020, and all BOINC versions from v7.16.4 onwards should be shipped with the updated files, and should work properly. If you're having a problem with (one only?) copy of v7.16.11, we may have to look further.

It was working on 3 SIngle Board Computers and 1 day stopped working. They weren't crashing, they just wouldn't communicate over the internet. Would not download new tasks or upload completed tasks. No changes to the network. The only thing I can think of is that Windows 10 did some automatic updates and that might have broken BOINC. Funny thing is that I have the 64bit version of BOINC running on 2 Windows Surface Pros running up to date Windows 10 and there are no issues. They are running now so I am happy. If there is something you would like me to try on one of the ones that wasn't working or information you would like, let me know. I'll be glad to assist in troubleshooting.

Thanks. Missed that. Most forums subscribe you automatically to topics you start or reply to so I didn't look for that.
