@amcasey @MackinnonBuck Any updates on this? I'm running into the exact same issue now. I'm using VS 2022 17.10.4 and this happens with a clean project created from the Blazor Web App template with "Server" render mode.

@amcasey or @MackinnonBuck - As of today this is still an issue with a Server render mode app created anew from the template. The VS 2022 version is Version 17.12.0 Preview 2.0 and the dotnet SDK version is 8.0.303. The error we see int he MS Edge browser tools is: WebSocket connection to 'wss://localhost:44376/HPortal/' failed: WebSocket connection to wss://localhost:44376/HPortal failed: | (anonymous) | @ | aspnetcore-browser-refresh.js:268
