Ex2 ultra snmp

i have a nas ex2 ultra.
on this nas i try to activate the snmp server on v2c.
only this one does not start, now I thought to reboot the nas to activate the settings.
this seemed like a solution because the smps started sending the information.
only this was of short duration after a minute the information stopped, until I restart the nas.

does anyone know what the problem may be.

thank you in advance

Hi bce626,

You can refer below article for SNMP Troubleshooting in My Cloud device.

thank you for the response.
but I tried that too, the result is the same.
snmp starts and stops after about one minute.
I think it is a software problem, because I have also set the port forwarding to udp 161
