Can't get SNMP checks working

Good Morning from Karlsruhe/Germany wink,

i'm doing my very best for days to get SNMP-Scan feature working properly, but I'm now at a point where I really can't go ahead.

I'm running Unix-Agent 2.10.0 on Debian (installed from packages). Inventory and IP-discovery works great. The SNMP checks are activated and the module is loaded properly. Ocsinventory is also telling me to do SNMP-scans, but actually it does nothingsad

[Mon Oct 30 09:57:58 2023][debug] [snmpscan] End snmp_end_handler :)

10.0.10.11 and 10.0.10.12 are definitely SNMP-devices which can be queried from the machine using snmpwalk.

I verified by using tcpdump on the machine that are are no snmp-calls done to the Hosts at all.


my setup:

I installed and configured everything as described in Using SNMP scan feature and Managing SNMP on Web Console however I noticed that documentation seems to be at least partially outdated. e.g. i found in newer threads saying snmp_com.txt is not used anymore and the documentation does not mention SNMP Type conditions at all. 

modules.conf:
# this list of module will be load by the at run time
# to check its syntax do:
# #perl modules.conf
# You must have NO error. Else the content will be ignored
# This mechanism goal is to launch agent extension modules
#use Ocsinventory::Agent::Modules::Download;
use Ocsinventory::Agent::Modules::SnmpScan;
# DO NOT REMOVE THE 1;

Even I have the same issue. SNMP auto discovery is not happening. Is there a way to add the snmp devices manually? Or any other workaround. TIA.
