Error message: API Error:Decryption of SNMPv3 password failed.
Hello,
I get this error message every time when I run it with a new snmp host connection test. It appears directly on all check windows, so I guess it is an internal checkmk error. I tried differnet passwords but it does’nt change anything.
The error also appears when I run the test on working snmp hosts I added some time ago. So I guess there was a change in one of the last updates that causes this problem.
