We recently upgraded our NagiosXI Server to version 5.7.1. It looks like this NagiosXI update doesn't communicate with NRPE agent (version 4.0.3) on our linux servers. We're getting this error: CHECK_NRPE: Receive header underflow - only 0 bytes received (4 expected).

Can you help me?

Thanks,

Tu

This post is very similar to https://support.nagios.com/forum/viewto ... 08#p313108, so I will be closing it to avoid confusion.
