Problem Accessing the RouterOS

Hello everyone,

I really need some help or thoughts on this because i am really confused. I have one Mikrotik Router which the last hours refusing to identify me with the same credentials i am using months now.. I tried with Winbox,webFig,ssh but i am getting the same error: “username/password invalid.”

Prior to that yesterday i had an electricity cut out for too long and the UPS managed to keep the router live for a few hours until finally went off.
Also, i have VPN server running on that router which i am able to connect get leases etc.

Do you have any clue what’s going on?

Maybe backup partition booted because of fastly repeated on-off power cycles. Check it.
