schedule refresh issue in report server data source is SharePoint

[Shrujan1612]

I have published a file in report server.  It is failing to refresh as per schedule due to login failed error, because of which, I am manually refreshing the data from my desktop application and republishing the dashboard.

I am able to connect the data source accurately without any error and the Service Id password has been updated (see below)

However, the scheduled refresh is giving me the below error. I have cleared all the permissions from the data source settings and republished. Can you help resolve this issue?

Thanks! in advance.
