The description is quite obvious (is there a loop)
Without you telling us what is connected to the ports it is very difficult to tell what is going on.

thanks for the reply…

For info…no physical connection connected/plug in to both port… port 2 and port 3…

As shown both port shown signage RS and link ok but no physical connection connected…

Even if I plugin direct from computer/device to that port, no data/can’t do anything i.e winbox of webfig…poe port function efficiently, can power up mikrotik device…

Thanks again for any comment

I would try to re-install RouterOS and if that doesn’t help I would contact MikroTik support or your supplier because I assume it could be a hardware fault.

already refer with distributor/reseller, nothing can do since distributor suspect over voltage incoming power/current to the routerboard…ask me to buy a new one since already expired warranty…huhuhuhu

Any feedback/comment/experience issue like this…thanks in advance
