I am testing some web parts in SharePoint 2019 that were developed for SharePoint 2010. I have installed Visual Studio 2019 on my dev server, and the projects have been upgraded when Visual Studio offered to do so.When I try to deploy a web part, I get the error: "Error occurred in deployment step 'Recycle IIS Application Pool': Cannot connect to the SharePoint site: http://ehnordic/default.aspx/
. Make sure that this is a valid URL and the SharePoint site is running on the local computer. If you moved this project..."
I have double-checked the URL (it is an internal URL) and it is correct. Then why do I get this error?
