MQTT.tool no connection to MQTT server

In my struggle to get my SIM7600 connected to thingspeak using MQTT, i went to the basics: simple testing of my connection:
I use this site : https://testclient-cloud.mqtt.cool
Protocol :tcp
Host : mqtt3.thingspeak.com
Port : 1883
Username : got it from my device (double checked !)
Password : got it from my device (double checked !)
When i try to connect I get the message Connection refused : bad user name or password.
I am completely lost. What basic stupi mistake am i missing. I thoroughly read the MQTT help pages.
Any help is appreciated.
Update :
When i select Dedicated connection and i also fill in the will message and will topic, i am able to update my channel. At least some progress.

Having the exact same problem, have you found any solution?
Suggest testing via desktop client.
Will and testament not supported by thingSpeak broker, so that might be an anomoly.
I dont see the clientID in the above settings.
