Locked myself out from website with defender


Im have defender installed and after new update of plugin i activated the new IP blocking tool.
I was then looking in media files where i see some files not showing, then trying to open and see what image this should have been.
Just after a few click in these media files, then site updated and told me:
You have been locked out due to too many attempts to access a file that doesn’t exist.

This i understand, but what i want to know, is how to come back to my site again?
Can i delete this blocking in the db or how can i be "accepted" for site again?
