Visual Studio 2022 17.3.0 hot reload I get this error very often. Both in Edge (Version 100.0.1185.44 (Official build) (64-bit)) and Chrome (Version 104.0.5112.81 (Officiell version) (64 bitar))
Most irritating since it's not updating page after save.

asp.net core 6 MVC web project.

    Still an issue with 17.3.6 and not just with Hot reload.
    It happens to me when a page redirects in a post.

    This looks like an open issue with the aspnetcore project: https://github.com/dotnet/aspnetcore/issues/45041
