Router is disconnected error

Hi Experts…!!!

I was browsing the function of the Mikrotik CRS125-24G-1S-RM router from the web interface.

When I click the the Add new option under NAT>Firewall>IP , I suddenly lost the access to my router.

Now I don’t know how to get back the access of the router Please help me in this regard.

I’ll be very thankful to you…!!!

Try to connect with winbox.
