Network errors when refreshing an app repeatedly

[javiercn]

I created a blazorserverside app using the latest sdk from core-sdk

dotnet new blazorserverside
dotnet run
Open chrome
Press F5 repeatedly at some point a request will fail and the UI will change.

Can you confirm the runtime version you were on? (ye olde dotnet --info output)

[javiercn]

This seems to be on the latest sdk

sdk\3.0.100-preview7-012605\ Host (useful for support): Version: 3.0.0-preview7-27825-01 Commit: afd0301944

F5 aborts requests that are in progress so some networking errors are expected. What makes you think there is a bug here?

Do you have server logs to go with this?

[analogrelay]

Should there be an ERR_SPDY_PROTOCOL_ERROR when F5 aborts a request though?

I don't think it's the abort. Once I get a repro, I can press F5 once and it repros (with no second F5 to interrupt/abort requests)

Seems to be HTTPS only Of course it is, it's an HTTP/2 error 🙄. I still blame @davidfowl ;).

Wireshark PCAP and Chrome Network Trace: https://microsoft-my.sharepoint.com/:f:/g/personal/anurse_microsoft_com1/EhcT4nYxsfFDqriQY3xDiiUBUws9dh385-BZw_-D41M4Yg?e=qYUlHw (MSFT-internal link)

Let's try bisecting out the HTTPS changes and the Bedrock changes and see if this repros there. @halter73 can you do that and see if we can either fix it or revert the right thing and try again in preview 8.
