SNMPERR_UNSUPPORTED_SEC_LEVEL (error SNMP # -34)

Trying to monitor a FortiWLC using MIB I downloaded. Imported the MIB converted to OID with PRTG software. Setup snmpv3 on WLC gettign this error#-34 when trying to add the snmp library. Ive also used SNMP tester im getting the same error when testing "Read Device Uptime" and "Scan Interfaces" on the tester.

Set SNMPv3 User
Set Auth-Key & Protocol "DES"
Set Priv-Key

These settings were set into Wireless Controller and PRTG/tester

Here is the out put from the PRTG tester
