HiveMQ-Cloud get ssl fingerprint / cert for MQTT

I'm trying to use the hivemq-Cloud service (https://console.hivemq.cloud/). Unfortunately I'm forced to use the ssl option and I can't figure out how I can download the public key / fingerprint.

Somebody familiar with the service?

I created a cluster and got something like this somehash.s1.eu.hivemq.cloud:8883 then I created a user and testet the connection with this service: http://www.hivemq.com/demos/websocket-client/. It only works with the option 'ssl' enabled.

I thought I can catch the fingerprint via ssh-keyscan:

ssh-keyscan -p 8883 <somehash>.s1.eu.hivemq.cloud
<somehash>.s1.eu.hivemq.cloud: Connection closed by remote host
<somehash>.s1.eu.hivemq.cloud: Connection closed by remote host
<somehash>.s1.eu.hivemq.cloud: Connection closed by remote host

And I got this message. How can I get the public key from a himemq-mqtt service?

Didn't worked for me with keyscan but with openssl. Here is the solution for my problem: Get certificate fingerprint of HTTPS server from command line?

openssl s_client -connect <somehash>.s1.eu.hivemq.cloud:8883 < /dev/null 2>/dev
/null | openssl x509 -fingerprint -noout -in /dev/stdin
