Just in case: there have been some mistakes in NUT codebase for SNMPv3 (or
rather AES) support found and fixed during the past year, so the errors
could be already in a 2.7.4 release (did not check for that). Do you have a
chance to build current master branch from github and see if it works
better for the SNMPv3 case?
Alternately, it was not clear from your message if you had also tried NUT
connection with the SNMP v1/v2c (and then a correct community name,
otherwise SNMP server usually seems just AWOL and not responding)?
>From your SNMP walk, it seems that the card does support at least the
standard IETF upsMIB, so at least to some extent snmp-ups should recognize
it barring the network/crypto issues.
