Snmptrap not receiving any messages

Hey,

our checkmk instance has the event console enabled and is listening for incoming messages via
snmp traps on (udp/162). When testing sending a snmptrap message from the checkmk host itself nothing is being logged and no events/messages are shown in the event console > events page.

Nothing is logged in the OMD[infrastructure]:~$ tail -f var/log/mkeventd.log either.
I confirmed that the host is listening on udp/162 and no local firewall is running.

snmptrap -v 2c -c public localhost '' 1.3.6.1.4.1.8072.2.3.0.1 1.3.6.1.4.1.8072.2.3.2.1 i 123456

Any idea what I’m missing?

CMK version:
Checkmk Enterprise Edition 2.2.0p24
OS version:
RockyLinux 8.9
