I found the solution, problem as in the server. I had to add the JwtBearerEvents in my AddJwtBearer Method:

    services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
        .AddJwtBearer(options =>
        {
            options.Authority = "https://securetoken.google.com/" + firebaseConfig.AppId;
            options.TokenValidationParameters = new TokenValidationParameters
            {
                ValidateIssuer = true,
                ValidIssuer = "https://securetoken.google.com/" + firebaseConfig.AppId,
                ValidateAudience = true,
                ValidAudience = firebaseConfig.AppId,
                ValidateLifetime = true
            };
            options.Events = new JwtBearerEvents
            {
                OnMessageReceived = context =>
                {
                    var path = context.Request.Path;
                    if (path.StartsWithSegments("/chat"))
                    {
                        var accessToken = context.Request.Query["access_token"];
                        if (!string.IsNullOrEmpty(accessToken))
                        {
                            context.Request.Headers.Add("Authorization", new[] { $"Bearer {accessToken}" });
                        }
                    }
                    return Task.CompletedTask;
                }
            };
        });
