When I run my server side Blazor app on development machine in Visual Studio code everything works fine. But after deployment to a Linux server with Apache2 there is a problem with WSS:// SignalR connection from client to server.
Running Root page of https://shop.gastroblitz.de/ results in Console Error:
Firefox kann keine Verbindung zu dem Server unter wss://shop.gastroblitz.de/_blazor?id=P1LOmrVSgCD4fAWd9lAhHQ aufbauen. blazor.server.js:1:30021 [2019-07-17T14:58:20.948Z] Error: Failed to start the transport 'WebSockets': null
I have reverse proxy configuration that redirects - https:// calls in server to http://localhost:5000 (where dotnet service is hosted) - wss:// calls into ws://
seems to work fine on https:// but I don't get work the SignalR thing which is initiated with wss:// and results in the upper error...
Using Visual Studio newest preview and dotnetcore-preview6.
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
SqlHub.ConnectionString = Configuration["ConnectionString"];
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
services.AddRazorPages();
services.AddServerSideBlazor();
services.AddScoped<OrderState>();
services.AddScoped<StoreData>();
services.AddScoped<BasketManager>();
services.AddBlazoredModal();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
//app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapBlazorHub();
endpoints.MapFallbackToPage("/_Host");
});
}
I want to have the whole Blazor app on the server like it is running in my Visual Studio environment. Would be great if someone has an useful hint regarding SSL / wss and all the configuration stuff... thx!
