Hi @arctrus ,
Thanks for sharing this. Your local deployment might fail due to insufficient resources:
Does your hardware meet Minimum Hardware Requirements?
For connecting to the HiveMQ Cloud broker you need to enable TLS, specify port 8883, supply Username and Password. Your client should have the TLS extension Server Name Indication (SNI) enabled. Please refer to this post that explains how to check this.
I hope this helps,
Dasha from HiveMQ team
