Was it old RouterOS version? If so its likely been hacked. Good news is, being old version you can use the same hack to re-gain access - but once its been compromised you should take config export, make sure no bad config is in there, and do a fresh net-install.
this issue keeps happening to me when my winbox version is to old for the used RouterOS version - just try to update winbox before you do anything else.
@mikrotik:
please add a more usable error message because even though it happened to me a couple of times I am regularly confused for some time before I figure it out again.

WinBox v3.18 doesn’t connect to RB with empty password out-of-the box.
Just login via WebFig / SSH / telnet and set a password (may even be empty).
WinBox login w/o password seems to works fine..
i can’t confirm this - i am pretty sure I did exactly that last week
