ping radius server from nas
Also, check mtik logs... you can turn on radius debugging in mtik and you will see what is the problem...

If yes, then probably you tell mikrotik that radius IP is the
secondary address while freeradius sends replies from primary IP
address. There are some ways to fix this, but the easiest way is to
set your NAS (mikrotik) to use the radius server's primary IP address.
