SNMP problem - noSuchName in Services while trying to get data from UPS

Yes. I Use distributed setup - I Have 2 servers with cmk, I’m running cmk command on machine with access to my ups - but it’s a slave machine.

Config seems to be ok, I’ve just created completely clean cmk install and have the same issue.
Also - Different snmp machines works correctly (I have snmp switches and some other machines working as it should)

So. From master machine i’ve got also no output from this command.

and from proper machine, -D option pops this out:

cmk -D UPS-socomec-rack
