Hello!
After some time of using version 2.0.0p3 we faced strange issue with the services state.
Checking service in dashboard shows "Unknown" state:
If I'll perform Full Scan - zero vanished services will be found and the same service will be in the "OK" state:
I tried to move this service to “Undecided” → Apply Changes → add service back → Apply Changes = same result.
Also tried to use: Actions → Remove all and find new.
Interesting that If I'll create copy of this host and scan it for services, the same service will be shown as "OK":
Configuration on the device exist and service should be in the OK state:
ru-spb-csw-01#sh run int vlan 1339
Building configuration…
Current configuration : 279 bytes

interface Vlan1339
description intVL1339
ip address 172.31.26.129 255.255.255.224
ip helper-address 172.31.9.24
ip helper-address 172.31.9.23
no ip redirects
no ip unreachables
ip verify unicast source reachable-via rx
end
I checked all rules that apply to this host/interface, not found any that can affect interface state.
