I have connected an external data source to Salesforce to fetch data. The data was getting fetched properly.Currently when I am logging into the application it is showing an Internal Error.Also in the query editor the data is not getting fetched.An error is thrown up :-
"[object Object]: You don't have permission to view this external data. Update your credentials, or contact your administrator for help with authentication settings. Error received from the external system: 401"
I tried resetting my login password but no luck.
I am using the Named Principal Identity Type with Password Authentication.
