Error Connecting using MQTT client

Hi
I have tried using the HiveMQ & the Eclipse Paho clients to connect to TTN but get an error on both: Failed to connect: AMQJS0007E Socket error:undefined.
I am using the Application ID as username and the Application Access key as password. The host is set to: eu.thethings.network and port is 1883.
Is there something that I should be doing in the TTN console before trying to connect.
Am I correct in assuming that TTN is acting as an MQTT broker?

Any chance you’re trying to use web sockets? TTN’s MQTT broker does not support those. (And brokers that do, probably won’t expose those on port 1883?)

Yes those clients are using web sockets.
I have seen brokers using 1883 for web sockets. There does not seem to be a port defined for web sockets specifically…https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=mqtt
But thanks for the info. I guess that is why it does not work
