Unable to refresh power query data source. Scheduled refresh is disabled (Credentials)

Hi gurus,

I have created a report using Power Query connected to a SQL Server Analysis Cube.

On my desktop PBI I can refresh the data source with no problem.

Once I publish the report into PBI Services, does not let me. It says:  Scheduled refresh is disabled because at least one data source is missing credentials.

When I try to check the credentials only gives me this option:

which once I select sign in does not do anything, just thinking for ever.

Not sure why my credentials are not working anymore the moment I Publish the report? any suggestion.

I need to update the Power Query.

Thanks in advance.
