UNKNOWN in Zapi invoke cannot connect to socket

[mvrgotiks]

Hi,

I am experiencing the following plugin output with all check_cdot commands, using NetApp-manageability-SDK 9.7.x-9.8.x.

UNKNOWN: in Zapi::invoke, cannot connect to socket

This is presented when running as Icinga, but when executed from command line, it works.

Any ideas?

transport type is HTTPS
