I need to establish a secure connection to an MQTT broker via Port 8883. To achieve this, I need to import and install the TLS/SSL certificates provided by our server team. Could someone please guide me on the correct procedure for importing these certificates into the TIA Portal environment and deploying them to the CPU? Thank you for your time and assistance.
