MikroTik SNMP traffic for PRTG

I am unable to retrieve SNMP traffic on PRTG Monitoring from MikroTik RB201 1Ui AS-RM. I enabled the SNMP on the router and created a community. I am able to get ICMP traffic but not SNMP. My local LAN is 192.168.10.0/24 and my PRTG is located at 192.168.88.0/24. I am able to communicate between 10.0 and 88.0 networks.

Flags: * - default

Error message: Could not create the sensor SNMP Traffic on device 192.168.88.1. Sensor does not get response from device, SNMP credentials are wrong or device does not support the required update OID for traffic sensors. This OID is mandatory by the SNMP RFC. Check SNMP access rights or contact device vendor. (code: PE244)

Could you please assist/advise?

Thank you
