Mikrotik HotSpot Service issue.

Hello,

i configured hotspot network with static private ip configured at user end

and they are getting authenticated by custom portal

Once authenticated, user gets 1:1 NAT with specific pool

Now for some of the users i am not getting host entry in IP>Hotspot>Host

and if i ping to those specific users IP from Mikrotik i am getting reply from another ip

which is supposed to associate with users post authentication

this issue start with one users and gradually it increases to multiple user

and the strange thing is on disabling/enabling hotspot service or changing the IP of user issue gets resolved but it impact on other users services

also i observed one error on this event occurrence log: “Internal Error:Fail to grant access”
