We are having an issue polling our hosts using SNMPv3 with SHA and DES. We have the issue on more than one host and more than one item. We can use SNMPwalk from the zabbix server and this works as expected, but in Zabbix we get the error Cannot connect to "X.X.X.X": Authentication failure (incorrect password, community or key).

Attached is a

1. A screenshot showing the working snmpwork
2. A screenshot showing The settings an affected item
3. A screenshot showing The macros configured for SNMP authentication for an affected host
4. A screenshot showing The error message in Zabbix

Thanks
