@mkArtakMSFT Issue seems isolated to Blazor - as @Thepriestdude indicated, MAUI App (without Blazor) functions perfectly.

[jasonsturges]

Likewise, same socket error for iOS simulator while other targets of Android and Mac Catalyst work.

Create a new MAUI Blazor App, and launching the template fails with white screen and mirrors the socket error of the original post here in this issue.
