Host unreachable in https due to weak Http2 cipher #8952
Description
Describe the bug
The browser is not happy with the cipher used for HTTP2 (i guess)
ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY and equivalent in chrome
Bad Workaround
only for firefox
i managed to go in about:config and disable weak cypher check this actually has an effect
is there a simple way to completely disable HTTP2 via a Kestrel IOptions<> ?
To Reproduce
Steps to reproduce the behavior:
- uninstalled ALL sdk
- removed folder from program files/user/appdata/temp
- install sdk
2.2.105and3.0.0-preview3from https://dot.net - version of ASP.NET Core : the one shipped with preview3
dotnet new webapi -n foo- comment out
UseHsts - comment out
UseHttpsRedirection() dotnet run --project foo.csproj- hit the
httpendpoint => works - hit the
httpsendpoint => rejected
Expected behavior
i tried to :
dotnet dev-certs http --cleandotnet dev-certs http --trust- delete
.vs/ - change
launchSettings.jsonto anything else - removed
UseHttpsRedirection() - removed
UseHsts() - not working for IP / dns in the browser
pretty sure all i did was update Vs2019, it was workign 2 weeks ago on the same SDK (or the latest win10 insider - fast ring update)
