Im not using IPv6 on the network (no IPV6 configuration on uplink MX no IPv6 configuration in LAN).
Still it seems that MR45's trying to reach IPv6 radius server when serving 802.1x WLAN clients:
auth_mode='wpa3-802.1x' vlan_id='100' radius_proto='ipv6' radius_ip='fd0a:9b09:1f7:1:9a10:d693:9c81:f130' reason='eapol_timeout' radio='1' vap='3' channel='48' rssi='30'
Is it expected behavior?
