6.40.5 SNMP encryption does not work

Hi!
When I enable SNMP encryption, the interfaces arbitrarily disappear from the list (Dude map->Device->SNMP->Interface) and links loading is not displayed
SNMP authentication works fine.

Most likely it happens because of the conflict use the same ports in your system configuration.

A standard snmp port is used…
When I switch snmp to encryption mode, the interfaces disappear in the list.

PS Forgot to say, I monitor the Mikrotik (6.40.5) devices using snmp. hAP lite and CHR.
