Arduino failing to connect to IBM Watson IoT over wi-fi. What am I missing?

Question

I have been spending some time on this but have had no luck, it should be something simple...

I want to connect to the Watson platform and send an event (some text) from an MKR1000 Arduino.

I have fallen at the first hurdle as it is not connecting to the cloud.

The info they have online is pretty good and has kept me in reading for a day or 2 now!

If I could get a second pair of eyes it would be great.

The wifi connection itself is ok as I ran it on a different code to confirm it was ok. Also, I am receiving a "?" to the serial monitor so assume that it is the cloud connection and not the wifi.

void connect() {
    Serial.print("checking wifi...");
    while (WiFi.status() != WL_CONNECTED) {
        Serial.print("!");
        delay(1000);
    }

    Serial.print("\nconnecting...");
    while (!client.connect("d:slqo8v:Arduino:Sender01","use-token-auth","<as 
    on the hub>")) {
        Serial.print("?");
        delay(1000);
    }

    Serial.println("\nconnected!");
}

I have reduced the security settings on the cloud to TLS optional. I have triple checked the login details.

The majority of the code is as below, I loath to post it all up as it says not to paste entire code but I don't think my experience is enough that this is not something trivial like a misplaced bracket.

The example I have been shown is like

client.connect("clientID", "username", "password")
IBM Bluemix 
clientID = "d:<slqo8v>:<Arduino>:<Sender01>"
username is aways: "use-token-auth"
password is: Token auth provided by Bluemix
Example:
client.connect("d:iqwckl:arduino:oxigenarbpm","use-token-auth","90wT2?a*1WAMVJStb1")

I have reproduced as this..

    Serial.print("\nconnecting...");
    while (!client.connect("d:slqo8v:Arduino:Sender01","use-token- 
    auth","as provided online")) {
        Serial.print("?");
        delay(1000);
    }
    Serial.println("\nconnected!");
}

void setup() {
    Serial.begin(9800);
    WiFi.begin("", "");

    client.begin("slqo8v.messaging.internetofthings.ibmcloud.com", 1883, net);

    connect();
}


void loop() {
    client.loop();

    if (!client.connected()) {
        connect();
    }
}

I have switched the code around also but haven't come up with anything workable.

Any help much appreciated.

Thanks!

Hello, no error messages. It compiles and uploads it just doesn't seem to want to connect to the ibm server. — Tam, Nov 05 '19 at 12:58

Looking at the server side I can see that the lastest errors are due to a space in the client id resulting in an not authorized error. The clientid being used is d: slqo8v:Arduino:Sender01 Note the space before the slqo8v.

I can't see that space in your code example so maybe it is special character from a copy and paste? or the code has changed since this post?
