    hi

    Can you share a simple project to reproduce?

    hi

    This seems to be a problem with https://github.com/Azure/azure-signalr.

    But you can try the code below to fix it.

    app.UseAuthorization();

app.Use(async (httpContext, next) =>
{
    var authenticateResultFeature = httpContext.Features.Get<IAuthenticateResultFeature>();
    if (authenticateResultFeature != null && authenticateResultFeature.AuthenticateResult == null)
    {
        if (httpContext.User.Identity?.IsAuthenticated == true)
        {
            authenticateResultFeature.AuthenticateResult = AuthenticateResult.Success(new AuthenticationTicket(httpContext.User, httpContext.User.Identity.AuthenticationType!));
        }
    }

    await next(httpContext);
});

app.UseSwagger();

    hi

    Please change your OnApplicationInitialization method by follow:

    public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
    var env = context.GetEnvironment();
    var app = context.GetApplicationBuilder();

    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseAbpRequestLocalization();

    if (!env.IsDevelopment())
    {
        app.UseErrorPage();
        app.UseHsts();
    }

    app.UseCorrelationId();
    app.UseAbpSecurityHeaders();
    app.UseStaticFiles();
    app.UseRouting();
    app.UseAuthentication();
    app.UseAbpOpenIddictValidation();

    if (MultiTenancyConsts.IsEnabled)
    {
        app.UseMultiTenancy();
    }

    app.UseUnitOfWork();
    app.UseDynamicClaims();
    app.UseAuthorization();

    app.Use(async (httpContext, next) =>
    {
        var authenticateResultFeature = httpContext.Features.Get<IAuthenticateResultFeature>();
        if (authenticateResultFeature != null && authenticateResultFeature.AuthenticateResult == null)
        {
            if (httpContext.User.Identity?.IsAuthenticated == true)
            {
                authenticateResultFeature.AuthenticateResult = AuthenticateResult.Success(new AuthenticationTicket(httpContext.User, httpContext.User.Identity.AuthenticationType!));
            }
        }

        await next(httpContext);
    });

    app.UseSwagger();
    app.UseAbpSwaggerUI(options =>
    {
        options.SwaggerEndpoint("/swagger/v1/swagger.json", "AzureSignalRPoc API");
    });
    app.UseAuditing();
    app.UseAbpSerilogEnrichers();
    app.UseConfiguredEndpoints();
}

    Hi maliming,

    That last change you suggested was the solution. Everything appears to be working now.

    Right now I have that code in OnApplicationInitialization and these settings in appsettings.json

    "Azure": { "SignalR": { "Enabled": "true" } }

    { "Azure:SignalR:ConnectionString": "Endpoint=https://xxxxxxx.service.signalr.net;AccessKey=xxxxxxxxxx=;Version=1.0;" }
