In your first screenshots you see that SNMPv2 is working and v3 not. I think the first discovery was done with v2 enabled and that’s the reason why you see the services but get no information now after switching to v3.
What i not see from your other posts - is this a RAW edition or enterprise?
If you use the enterprise i would test to switch the SNMP backend for this one host to the classic one. I had already some devices that had problems with the Python backend and where working without problem with the classic one. This was especially with SNMPv3 the case.
Ok, I made that change, and I get the following in connection tests
It is green for snmpv1/v2 but those aren’t configured. V3 is complaining about the password being too short, but it’s working, see second picture
