Hello there!
If you "deleted" your Lansweeper server, that would imply that you can no longer log in to the Lansweeper web console, and as such, you can no longer view any Lansweeper-related information.
It's not entirely clear how you deleted or uninstalled the Lansweeper server, but if you would like to double-check on the physical server if any information remains, you can find more information on where we store the data here: https://www.lansweeper.com/knowledgebase/where-lansweeper-data-reports-and-settings-are-stored/
