Refresh failed

Hello, I made a power bi report in power bi desktop. I can refresh it there without problems. I have the option to connect to my microsoft account.

Now I published to Power Bi Online to add the sheduled Refresh (this works perfect in my other power bi reports) But now for this report I just cant do it... I get the error : Your data source can't be refreshed because the credentials are invalid. Please update your credentials and try again

I click edit credentials but there I don't get the option connect to microsoft account (only anonymous and windows) I searched everywhere for a solution but can't find it... anyone got any idea how to solve this ?
