Attempt to access management:

I'm sure it's related to maintenance mode, I can not turn off, because I'm not as a manager, so maybe it's possible to turn off through the server?

If you can't get into the admin page you can run this from the cli to turn off maintenance mode.

db.objects.update({_key: "config"}, {$set: {"maintenanceMode": 0}});

Then restarte nodebb and it should be disabled.
