Troubleshooting The Error

This error is not to be confused with the error "CHECK_NRPE: Received 0 bytes from daemon" as they have separate causes.

Most often, this error is experienced when using the no ssl switch (-n) with check_nrpe even though NRPE on the remote host was compiled with ssl enabled. There are very few instances where NRPE is best run without ssl, so if you added the -n switch to your check for testing reasons, make sure to remove the switch before deploying the check. If you have a reason for not using ssl, do note that you will have to compile NRPE without ssl to avoid this error when using the -n switch. Detailed compile instructions can be found in the following KB article:

The other general cause of this error, though rare, happens when your check's check_nrpe timeout is set too low. To increase the timeout, refer to the following KB article:
