Core client errors

Scheduler request failed: peer certificate cannot be authenticated with known CA certificates

This error most frequently occurs because of incorrect date settings on your computer. To correct the problem, correct your computer clock.

Why does this problem only affect World Community Grid, and not other BOINC projects? This is because World Community Grid is (at the time of writing) the only BOINC project that requires a secure connection to the server. Other projects permit falling back to an insecure connection.

Scheduler request failed: problem with the SSL CA cert (path? access rights?)

This is a known problem with some ported BOINC releases, especially certain Linux x64 ports. The reason for the error is that a file (ca-bundle.crt) was omitted from the release.

If you see this error message in your message log, then you probably need to apply this fix.

1. Determine your BOINC data directory. Check the beginning of your message log. There will be a line near the beginning like this:

   08/06/2007 13:18:00||Data directory: C:\Program Files\BOINC
   

2. Download the missing file. - make sure you name the file ca-bundle.crt.
3. Place the file in your BOINC data directory.
4. Restart BOINC. The way you do this will depend on your installation.

Why does this problem only affect WCG, and not other BOINC projects? This is because WCG is (at the time of writing) the only BOINC project that requires a secure connection to the server. Other projects permit falling back to an insecure connection.

FreeBSD note: this issue has been fixed, please update your port-tree and rebuild BOINC.

Scheduler request failed: SSL connect error

This is a known problem with some ported BOINC releases. BOINC was dynamically linked to the curl library, but your installation of curl was compiled without OpenSSL support.

Example

Project communication failed: attempting access to reference site
World Community Grid|Scheduler request failed: SSL connect error

Solution

Recompile curl with OpenSSL support, or reinstall it with OpenSSL support enabled.

Workaround

If you cannot recompile curl, get a statically linked BOINC build.
