asp.net - Client can't connect to SignalR Hub (CORS does not work) -


my startup.cs in server (implementing cross-domain requests using owin.usecors):

public void configuration(iappbuilder app) {     app.map("/signalr", map =>     {         // setup cors middleware run before signalr.         // default allow origins. can          // configure set of origins and/or http verbs         // providing cors options different policy.         map.usecors(corsoptions.allowall);         var hubconfiguration = new hubconfiguration         {             // can enable jsonp uncommenting line below.             // enablejsonp = true         };         // run signalr pipeline. we're not using mapsignalr         // since branch runs under "/signalr"         // path.         map.runsignalr(hubconfiguration);     }); }

my client (console project):

static void main(string[] args) {     ihubproxy _hub;     string url = @"http://111.111.111.111:13098/signalr/hubs";     var connection = new hubconnection(url, querystringdata);     _hub = connection.createhubproxy("testhub");     connection.start().wait();     _hub.on("broadcast", x => console.writeline(x)); }

only when run client (console.exe) @ server (signalr project hosted in iis), can connect hub.

if run client @ computer, it not capable of getting connected.

why?

input http://111.111.111.111:13098/signalr/hubs @ chrome:

can enable jsonp , see?

var hubconfiguration = new hubconfiguration { enablejsonp = true };
