I am trying to create SignalR server with Xamarin client. Everytime i am trying to connect to server, the status is just "connecting" without change. Tried to bypass certificate with code i found on the internet but it does not solve the problem. And when I try to go on hub site (ip:port/notifier) i get message "Connection ID required"
Client side:
public class SignalRService : ISignalRService
{
private readonly HubConnection hubConnection;
public SignalRService()
{
hubConnection = new HubConnectionBuilder()
.WithUrl("https://ip:5001/notifier", options => {
options.HttpMessageHandlerFactory = factory => new HttpClientHandler
{
ServerCertificateCustomValidationCallback = (message, cert, chain, errors) => { return true; }
};
})
.WithAutomaticReconnect()
.Build();
}
public void /*async Task*/ Connect()
{
hubConnection.StartAsync();
var a = hubConnection.State;
while (hubConnection.State == HubConnectionState.Connecting) //for debug purposes
{
continue;
}
a = hubConnection.State;
}
Server side
public void ConfigureServices(IServiceCollection services)
{
services.AddRazorPages();
services.AddSignalR();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapRazorPages();
endpoints.MapHub<NotifyHub>("/notifier");
});
}
Thanks for any help!

So finally I found a solution!
the problem was that emulator cannot connect to localhost through http://localhost:port but with ip "10.0.2.2:port"
and for some reason implement signalR to client as service did not work aswell...
