swood12345 I think we may have different issues. My issue is not related to Power BI Desktop. I'm doing the following steps to get to the page where I no longer see an indicator that a data source is failing. Previously this page did show an indicator, but after the page was redesigned I no longer see an indicator.
1. Go to https://app.powerbi.com/
2. Go to Settings > Manage Gateways
3. The page has 3 different tabs. I'm on the Data sources tab. There is a Status column, but this doesn't show an indicator for which data sources have a connection that is failing. Previously you saw an indicator for a data source that failed to connect when it was used in a refresh of a dataflow or dataset.
I see there is an icon in the Status column to check status. I suppose next time I change my Microsoft password I will go through and click check status for each data source. It seems like an extra step to what we had before this page was modified.
I do notice Data (Preview) at the top of the page. I wonder if there is a way to go back to the old version of this page and not use the preview version of the page.
