Does anyone have a solution? We have the same exact problem.
We are using Check MK 2.0.0p19 (CRE) and have 5 ilo’s with the same status, the other 45-50 ilo’s are working like a charm. All our ilo’s are behind VPN tunnels.
3 ilo’s are using firmware 2.77, 1 ilo is using 2.78 and the last one is using 2.79.
We also tried updating the firmware from 2.77 tot 2.79 but that doesn’t fix it, neither resetting or clearing the logs.
Even creating the same host in check mk doesn’t fixt it or deleting the old and then creating a new.
None are connected\registered to HPE.
All have a valid ssl certificate within the ILO.
We are using SNMP v2 (not tested v3) and always change the snmp community string.
I’m not totally sure but I think the problem started after updating check mk to version 2.x from 1.6.x and then adding new hosts to check mk.
