Can hivemq support one way authentication (Client verifies server) with free cluster? If it supports what are the certificates needed? server CA certificate alone is enough? I am trying to do this with SIM A7600C1 GSM module through its ATcommands, but it is not working. Have anyone tried this? If there is any step by step detailed procedure how SIM A7600C1 can be used for SSL-MQTT (oneway/) with HiveMQ free cluster including certificates generation, please share.
Hi @Murali ,
It is great that you are interested in MQTT and HiveMQ! Welcome to our community.
From your questions it looks that your device requires a server CA file to connect via TLS. How can you generate this for your HiveMQ Cloud instance?
You can download the root certificate here .
This will create a file called “isrgrootx1.pem”, which you can use as “Server Certiciate”.
What else is required? We require the TLS-SNI extension to be available and used. Please refer to this post, if you want to learn where to check if TLS-SNI extension is turned On in your SSL configuration: Client is not authorized to connect - #37 by simon_b
I hope this helps,
Dasha from HiveMQ team.
