Can't login by IP - not allowed to login from this address

Hello,

I have a problem with my RB960PGS, since yesterday, I cant login with winbox when I use IP instead of MAC. Winbox responds with ‘wrong username or password’. Same with HTTP interface.
When I try to connect from the Android app, I got ‘not allowed to login from this address’, so I checked IP->Services, but there is no restriction set and I’m on LAN.

I’m helpless, has anyone had similar problems?
Thanks
