Hello, i have one issue with downloading the server build 19504. Same with Server Core FoD app. can Anyone give a working link?
its a broken link. https://software-download.microsoft.com/db/Windows_InsiderPreview_Server_vNext_en-us_19504.iso?t=6de7eb80-7ad6-439d-8702-e9ec65ddf8f3&e=1634902816&h=2901e27545dcfd44e8e7fcaf8ec0a1dd 

Thanks for reporting. Looks like MS has removed the download. If that's permanent, I'll remove this option from the dropdown, maybe in a month or so.
