@semarie Hi,

Thanks for your help, I just created the user with the net-snmp-create-v3-user command, and definded SHA-256.

SNMP now works like before.

net-snmp-create-v3-user -ro -A verrysecureauthenticationpassword-a SHA-256 -X verrysecureprivacypassword--x AES snmpusername

Just updated 1 pool with 3 hosts.
SNMP did not work anymore, config file was not changed.
Got the following error: Authorization Error (SNMP error # 16)
Did a yum downgrade net-snmp*

From:

• net-snmp.x86_64 1:5.9.3-8.1.xcpng8.3
• net-snmp-agent-libs.x86_64 1:5.9.3-8.1.xcpng8.3
• net-snmp-libs.x86_64 1:5.9.3-8.1.xcpng8.3

To:

• net-snmp.x86_64 1:5.7.2-52.1.xcpng8.3
• net-snmp-agent-libs.x86_64 1:5.7.2-52.1.xcpng8.3
• net-snmp-libs.x86_64 1:5.7.2-52.1.xcpng8.3

After a service restart, SNMP worked immediately.
