I’m trying to execute Mosquitto_sub function, as described in Getting Started.
However when I run the command, I get following feedback:
Client mosqsub/9182-raspberryp sending CONNECT
OpenSSL Error: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
I tried to copy .pem file from here, but it looks it’s not accepted. What I’m doing wrong?
