On server with nrpe - no one connection. If execute with -n (withous tls), in debug only connection, on Shinken - CRITICAL (Error : Empty response from the NRPE server)

P.S.: shinken 2.4, module from .io

The same with Shinken 2.4.1, but status on WebUI does not changed.

I fixed this by installing the openssl extensions for Python:

pip install pyOpenSSL

@eltismerino, thanks!

[eltismerino]

Well I don't think this is a particularly good fix for this problem. The code seems to handle non-existing pyOpenSSL, but it doesn't seem to handle it well when the server expects an SSL connection.

It should be fixed in the code.
