MQTT TLS Client Certificate Create/Generate

Hi @splata,

HiveMQ cloud basic does not support mutual TLS so you do not need the files “Certificate” and “Private Key”
You can create the Server Certificate file using the OpenSSL s_client openssl s_client -connect 4ad85b7fade04d07911be2ac1da2f5e4.s2.eu.hivemq.cloud:8883 -showcerts < /dev/null 2> /dev/null | sed -n '/BEGIN/,/END/p' > server.pem
This will create a file called “server.pem”, which you can use as “Server Certiciate”.
I took the liberty and created the file for your specific cloud deployment.

Kind regards,
Florian from the HiveMQ Team.
