Objective-C can't connect to server

[programmerC]

Hello!

Please help me to solve this problem.

Thanks in advance!

Code: self.socket = [[SocketIOClient alloc] initWithSocketURL:url options:@{@"log":@YES, @"forcePolling":@YES, @"nsp":@"/im", @"ConnectParams":@{@"token":self.demo_Token}}];

[self.socket on:@"connect" callback:^(NSArray * _Nonnull data, SocketAckEmitter * _Nonnull ack) {
    NSLog(@"actNum:%ld",ack.ackNum);
}];

[self.socket on:@"system" callback:^(NSArray *data, SocketAckEmitter *ack) {
    NSLog(@"%@",data);
}];
