SLA Task problem

I am logged to my mendix account. I do the SLA Task App. When I do the Preview, it ask me to log in. I select “Mendix account”. I write my username and password. It keep telling me that “the username or password you entered is incorrect”. Can you tell me what is wrong? Thank you !

I don’t know what was wrong. When I tried it this morning it was working.

Thank you for your help!
