Here's a very simple Node-RED flow for a MQTT test using a FREE broker.  
This should test if your setup is working.

![quick_mqtt_test](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/2/72bfc90df99ee3323d96d4feaa2ad7a771e23001.png)  
If you click the 'Inject' node you should see this message arrive in the 'Debug' node.

As a starting point, import the Node-RED flow below and make sure it works for you.

You have given us next to nothing to go on @daniel90.

However, the gibberish in your Server field looks similar to my setup for HiveMQ.  
You need this info from [hivemq.com](http://hivemq.com)

And access credentials from

Then in Node-red

Finally

Well it works for me. Sorry about that.

Note that it only works if I have Use TLS ticked, as you see in my screen capture. But my TLS configuration has nothing except a tick against Verify server certificate.

As well as not having TLS ticked in 1st screenshot, you also have MQTT 3.1 legacy selected - change that to MQTT 3.1.1
