Hello,
This is the first time I am seeing this error. Most of my computers have been recieving and sending work fine. A few of my high core count or powerfull computers have been getting the following error:

6/20/2026 9:02:36 AM | Asteroids@home | Sending scheduler request: To fetch work.
6/20/2026 9:02:36 AM | Asteroids@home | Requesting new tasks for CPU and NVIDIA GPU
6/20/2026 9:03:07 AM | Asteroids@home | Scheduler request to http://asteroidsathome.net/boinc_cgi/cgi failed: Failure when receiving data from the peer
6/20/2026 9:03:08 AM | | Project communication failed: attempting access to reference site
6/20/2026 9:03:09 AM | | Internet access OK - project servers may be temporarily down.

Does anyone have any insight into why this is occuring? I tried to lower the work cache but these computers still will not connect and I have moved the computers to other project.

Thank you in advance!

Forgot to mention: I tried resetting the project in BOINC manager and still getting the same error. My other computers are receiving and sending working without issues.

You have many computers, so it would help if you specified which one is having issues.

If it’s a Mac, it could be a known certificate issue (fixed in BOINC 8.2.15)

Android devices may also require an update of the BOINC client.

If it’s neither of those cases, try enabling http_debug for more detailed logs. Can’t you connect to the server at all, or is it only happening occasionally? The server might just be busy...

Thank you for your response. Most of my computers are Windows 11 pro with a couple of older computers with Debian linux. Here is one of the computers: https://asteroidsathome.net/boinc/show_host_detail.php?hostid=815915

If the server was busy, would not my other computers also have problems downloading new work once in a while?
Looks like it contacts the server as it has a very recent "Last time contacted server" status of only a few mins ago. However, I continue to get the error and am not able to download any new work.

any proxies / vpns that could block the communication?

Windows hosts aren’t affected by the certificate issue, so the cause must be something else...

No, the computers are on the same network as others that have no issues. I believe it has something to do with the amount of work that the computer is trying to request or report. Larger amounts tend to give the error. I reduced the requested work cache and it seems to have improved although I still get the error on two of the computers.

Ok, I think this is an issue with the server being highly loaded. I am now having the issue on most of my computers and I am guessing many users are experiencing the same problem.

If anyone have a bunch of tasks that are completed and will not report, do the following:

1. Select "no new tasks" for the project and then click update. This should report all the completed tasks.
2. Reduce the work cache to something very low, ie 0.05 days - this will have a greater likelihood of getting work before the connection times out connecting to the server

Hopefully this works for anyone having the problem and is a temporary issue.
