Scheduler request failed: Server returned nothing (no headers, no data)

From BOINC Wiki
Jump to: navigation, search

The message "Scheduler request failed: Server returned nothing (no headers, no data)" is generally a message that the Scheduler "refused" the connection (Retry x.xx seconds later) or that your communications couldn't get fully through to the server.

Anywhere between BOINC 5.10.45 and 6.10.18 a bug crept into libCurl (which handles the communications in BOINC), that would corrupt the TCP/IP DNS stack that your OS (and thus BOINC) uses to know where servers are.

If you are still on an older version of BOINC, try to flush the DNS cache. In Windows this is done by typing ipconfig /flushdns from a command prompt.

Or update to the latest BOINC version. At the time of writing, BOINC 6.10.36 should be the new or upcoming recommended version.
