Read the error message, it's pretty clear:

Cannot find column [Server]

Then look at your filter:

...RowFilter = $"Server Like '...

The filter looks at your data source, and can't find any column called "Server" so it - rightly - complains.

I'd start by look at the data returned by the previous line in the debugger while your code is running...

Sorry, but we can't do that for you!
