data source credentials issues and unable to remove files data flow

[rachelb123]

The owner of this dashboard left the company and I have to manage it in the interim. I took over the credentials as their account became inactive and I keep getting errors on two of the web connections - My solution was to delete these web connections as they are not being used for the data flow. When I look in the data source settings - there is no option to delete it/unlink it. What do I do here? This data flow is the way the dashboard itself gets new data. Another issue I see is that one of the links having issues is an active file and that link works when i copy and paste it but the error says "Failed to update data source credentials: Web.Contents failed to get contents from "File Link" (404): Not found. Any help is appreciated thanks.

Hi @rachelb123 ,
Thanks for reaching out Microsoft Fabric Community Foum.

The best and most reliable fix is to first remove anything in your dataflow or report that is still using the old Web connection, then refresh the workspace, and finally delete and add the source again with new credentials. The reason this works is because the system won’t let you delete a data source if it is still being used anywhere. By opening the dataflow and temporarily removing or disabling the queries that depend on that Web link, you break that link so Fabric no longer considers it active. Once you save and refresh, the old connection becomes free, and you should now see the option to delete it in Manage Connections & Gateways. After that, you can recreate the connection cleanly using your own login. 
Thank you.

@rachelb123 Click on the Edit credentials link and enter new credentials?

I have already done that and these files do not exist in that location anymore so it just gives me a 404 not found error.
