I'm administartor of adboe and our school have 500 License.
But one student cannot login.
When he typing his password this error comes out.
I googled it, but I don't know why it happen.

Please confirm if the user is getting this error when signing in to the web account or to the application.
If it is a web account then I would recommend changing the browser or test it on a different machine. A screenshot would be helpful.
